Do you want a little fish like the one looking for nemo? Find out what species it is

Fish (from the Latin pisces) are primarily aquatic vertebrate animals, generally ectothermic (they regulate their temperature from the environment) and gill-breathing. They are usually covered by scales, and are equipped with fins, which allow their continuous movement in aquatic environments, and gills, with which they capture the oxygen dissolved in water. The Pisces group is not a taxon because it would be paraphyletic. Fish are abundant in both salt and fresh water, with species found from mountain streams (e.g., gobies), as well as from the deepest ocean (e.g., swallowtails).

Foods prepared with fish are an important source of food for humans. They can be large from wild specimens, or raised in a similar way to livestock (see aquaculture). Nowadays the so-called sport fishing is becoming more and more popular. Fish have played an important role in many cultures throughout history, ranging from religious deities to book and movie themes.

The specialty of zoology that deals specifically with fish is called ichthyology.


Utility of the fish

Fish are a group of animals of great economic and nutritional importance to man. The value of the catches is high.

The fish are used:

Decoration of aquariums


All those who enjoy having an aquarium at home have started this beautiful hobby for different reasons: to get a nice decoration for the living room, to have a new pet that is easy to maintain or to be able to create a new ecosystem from wax and get different species to live together in harmony. The important thing for those who enjoy this hobby is to experiment and improve day by day, to have healthy and full of life aquariums and at the end, those who go into this fascinating world, end up having a beautiful ecosystem that will delight everyone.

The greatest exponent of this philosophy of life is undoubtedly Takashi Amano, considered worldwide to be the best aquarium landscaper. Takashi Amano was born in Nigata (Japan) in 1954. His work is considered living art and his aquarium photographs are exhibited in prestigious galleries. He was the first to introduce Japanese gardening concepts and Zen to aquatic landscaping.

His compositions are combinations of river stones, submerged wood and aquatic plants. He does not add any element that we could not find in nature. And he doesn’t always create in giant tanks, but in 100-liter urns he creates truly wonderful landscapes.

If you have decided to try to set up an aquarium with natural plants, you can follow the advice that Amano gives in his books Nature Aquarium Word. All three are dedicated to freshwater landscaping, plants and fish. The tips he offers to create an aquarium as beautiful as yours are

To create beautiful clusters of vegetation, it is best to plant them in an odd way. This way we create movement and a harmonic imbalance, just like we find in nature.

Thin-leaved plants should be planted in the middle of the tank. Large leaves are better in the corners.

Although we tend to place the red in the center, it is better to leave it for the sides so that the whole looks dark.

Plants with dark leaves are better on the sides, those with light colors are better in the center.

We must not forget to create light and dark areas to give a feeling of depth and help the fish to choose their favorite corners.

We must not forget to create light and dark areas to give a sensation of depth and help the fish to choose their favorite corners.

Don’t be afraid to use colored sand (always within the natural ranges). Mix light and dark to create even more contrast. Use rocks or logs to hide the separation lines. You can also start by using substrate in sufficient quantities to fill the whole base. Remember that the back needs to be more inclined than the front, so you should accumulate at least 8 cm of substrate.

Use stones of different sizes and shapes, as it happens in nature.

The edges of the rocks must be round, without edges that the fish can hurt themselves with.

A good way to give naturalness is to hide the rocks with the plants totally or partially and use them as a base, more than as a decoration.

If you have a small tank, designs with a clear front, only with sand, are a good alternative. It is best that you start planting following a previously chosen design. Although there are those who advise to leave the baskets and the sponges of the plants, do not do it because you prevent their correct functioning. Do not forget to cut the longest roots before planting.

Use the fishing line or cotton to fix the moss to the rocks or trunks. A trick to perform this task and take care of the plants at the same time is to use a heating wire that will be placed at the bottom to control the temperature of the roots.

Anubias (one of the most popular types of plants) tend to escape, use rocks to keep the roots hidden so they can move with the current.

When planting, do it in a gradual order of size: Small plants in the front and bottom and increase the size of these as we move away from the bottom.

You should not prune your plants until after 3 months from planting and when you have to do it wait until the plants reach the surface of the tank and cut it approximately in half.

The back lighting should be from bottom to top.

A set of branches covered with moss will give a very pleasant effect in a simple way for the aquarium.

By following these easy guidelines you can completely change your aquarium. Remember before you start what you will need:

Some mistakes to avoid in your aquarium

Maintaining a small aquarium is not difficult and can provide many hours of healthy and relaxing entertainment. If you get caught up in this fascinating hobby, you will learn a lot about how to take care of fish and reproduce their natural environment, so that you will always have a fascinating part of nature at your fingertips. Avoid rookie mistakes with our advice!

1. The conditioning of the aquarium

It is advisable to avoid small, ball-shaped aquariums. They are not suitable for many reasons: they are too small, they do not allow good oxygenation of the water because the surface area is small in relation to the volume and their circular shape is stressful for the fish.
Choose a medium-grain gravel, because large stones accumulate a lot of dirt and small stones prevent water circulation underneath. This affects the quality of the water and is harmful to the fish. If you like colored gravel, look for a natural gravel, without colorants that can contaminate the water.
If you are going to house several fish, it is important to look for a suitable aquarium filter. This can be expensive, but the benefits are enormous: you will avoid disease, fish death, poor water quality, waste accumulation and create healthy water circulation within the aquarium. Ideally, you should use a filter with a capacity slightly larger than the volume of the tank, so you can be sure that it will be efficient.
Place some live plants in the aquarium. The plants consume the nitrates and thus complete the removal of the nitrogenous residues in the water. If you also have herbivorous fish, plants will be a healthy and natural food source.
Once you have created a home for your new pets, it is time to choose the fish. This is very important, because overcrowding causes stress and so much organic waste is generated that the filter cannot eliminate it at the rate it is produced. If ammonia accumulates in the water, it is toxic to the fish. On the other hand, choose , that they are not aggressive and that they have the same temperature and feeding needs.

2. Handling and maintenance of the aquarium

Do not over-clean the aquarium. Remember that the aquarium is a living environment, where each bacterium is part of the ecosystem and is necessary for the life of other species. Make partial water changes every 3-4 weeks or when the tests indicate it. Do not use products to clean the gravel, since a large amount of the bacteria that eliminate nitrogen is housed there. Simply remove some of the water from the bottom by siphoning it off and replacing it with clean, chlorine-free water.
The aquarium requires time until all the fish in it are balanced. You should not become obsessed with its care, as you will only stress the fish. All the maintenance tasks have an adequate frequency and if you are constantly relocating the ornaments, the gravel or the filters, you will not allow the ecosystem to prosper. Just relax and observe, you will get to know the personality of each fish and you will be able to tell if one is sick.

3. The health of the fish

The most important thing in the aquarium is to maintain the health of the fish. When you detect a problem the first thing you should check is if the water is in perfect condition. Many times this is the origin of the problem and there is no need to take medicine, just correct some details or make a partial water change.
In case of illness, avoid using too much medicine, as it can damage the health of your fish. Respect the doses and application frequencies indicated by the manufacturer. Do not mix and consult an expert before adding anything to the water. Unless there is a declared infectious disease, it is often preferable to create a calm environment with excellent water quality for the fish to recover naturally.
Finally, if you are a beginner in the world of fish, it is preferable to go slowly. Start with few fish, few decorations, learn and progress as you gain experience. This way you will achieve the aquarium of your dreams with the least possible loss of fish and making the most of your budget.

Remember that in the pet stores you will find everything you need to enjoy your fish to the fullest and give them the proper care. From the best aquariums and accessories for fish tanks to the most nutritious fish food.

What do fish eat?


As we know, the feeding of the fish is not the same in nature as in our aquarium. In their natural habitat, fish usually feed on other smaller aquatic animals such as larvae or invertebrates. Most of them are carnivores, although there are some species that feed on plants and algae. As for what fish eat when they live in a tank, it will depend on whether they are saltwater, fresh water, tropical or bottom fish.

It is very important to know the feeding of each species to offer them an adequate food that provides all the nutrients and vitamins they need to be healthy and live for many years.

What do tropical fish eat?

Tropical fish can feed on live and dry food: the first could be mosquito larvae, shrimp and small worms; the second can be flakes, granules or tablets. With them you provide a balanced supply of nutrients, fibers and proteins for optimal health.

In Tiendanimal you can find different options of food for tropical fish, supported by the best brands: Tetra, sera, JBL and Tropical are some of them. Food in flakes, Menu in flakes, granulates, microgranulates, floating food, larvae, fresh food in gelatin, spirulina and much more. In addition to vacation food and specific food for guppies or bettas.

What do coldwater fish eat?

Cold water fish are very easy to care for and maintain. There are many foods for each species adapted to their nutritional needs and their digestive system. The most common are floating sticks, granules and scales.

Complete formulas so you don’t have to worry about anything and don’t need any kind of supplement for your fish. Flakes and scales are the most common food for cold water fish: they stay in the water longer and are easy for the animal to reach. In contrast, the granules that the fish eat are heavier and go down to the bottom of the aquarium faster, so some less skilled fish will not take advantage of them. While scale remains can easily contaminate the water and must be cleaned frequently to avoid this, the granules leave little residue and maintain the balance of the aquarium.

The cold water fish food is suitable for species such as goldfish, bubble eye fish, betta splendens, telescope fish, comet fish, Chinese neon or Koi carp.

What do goldfish eat?

Food for bottom fish is not the same as that of fish swimming on the surface. Flake food is not suitable in this case, because we need it to weigh it down to the last level of the aquarium quickly and it is not eaten by others during the descent either.

We are talking about fish such as catfish (plectrums, catfish), coati and barbels. Round tablets and discs are the most commonly used food for these species because they are very heavy and can be deposited in specific areas of the tank. We have tablets for carnivorous fish and others with spirulina algae for phytophages. Tetra, sera and JBL satisfy the nutritional needs of these species with proteins, minerals and vitamins combined in a solid and compact format.

What do discus fish eat?

Discus are freshwater fish that are highly appreciated for their beauty but have a demanding diet that requires a greater variety of food. In addition to the classic granules and scales, the discus fish supplement with Tropical D-Allio Plus Granulat has vitamins, a high nutritional value and improves the digestive process; one of the star products for this species.

There are also sera color enhancers, designed to highlight the intense color of the discs with complete formulas consisting of a multitude of ingredients such as spirulina, green-lipped mussel, nettle, garlic, spinach and carrots. With Tiendanimal’s quality products your fish will be healthy and look splendid.

How to feed our fish during our vacations


One of the most common situations that people who share their life with an animal face is when you have to settle down for a few days at home or you go on a trip and you can’t take your pets with you. In the case of dogs or cats you can always leave them with a friend, family member or in a specialized daycare center but when it comes to fish it is not so easy. You’re going on vacation, and obviously you can’t take your fish with you. Moving and setting up an aquarium wherever you go is an impractical idea and almost impossible to do.

What can you do for your beautiful fish? Well, there are four options:

Do nothing while you are away. If your fish are well cared for and you are only going to be gone for a couple of days, most fish can go a few days without eating without any problems. Many species, especially some larger fish, will usually be fine if they are well fed and others that are less active can use one day of fasting a week so that their digestive tract can function properly.

However, it is important to be aware of specific needs of some fish, such as fry or sick fish, which may not be able to go many hours without eating in order to grow or recover.

Ask a friend or neighbor to help you feed your fish. It really is the best option, this will reduce many problems, especially when it is many days. If you are inexperienced, you can teach your fish how to feed them and leave everything organized in individual portions for each meal.

The third option is to get an automatic feeder which is usually a reliable method to keep your fish. However, try to practice with the devices a few weeks before so that you can observe not only how it works, but also how the fish in your aquarium receive it.

The last option is the food blocks, which are also an option. Although I personally don’t recommend them since they can make your aquarium dirty and unstable, if you finally decide to use this method, make sure it is appropriate for the number of fish you have, that it is in a large aquarium, that it has a good filtration system and enough scavenging species, the same as with the automatic dispenser, make sure you use it a few weeks in advance to really see how it works.

10 beautiful fish you can have in your aquarium


First of all, make sure that the species you choose can live together and know how difficult it is to take care of them.

Fish can be excellent pets in case we want to have pets but don’t have much room at home, time to spend with them or we are not ready to commit to the three daily walks a dog needs. These pets also do not dirty or can break anything. Also, if you have children they can learn what it is to be responsible for an animal with them.

In the photo gallery we propose you 10 species of fish of great beauty but before, we tell you some basic guidelines to take care of them.

Basic care of fish

Fish that get along. Let yourself be advised by an expert so that you do not make the mistake of mixing fish species that do not get along.

How many fish? Tell the expert the dimensions of your aquarium so that he can advise you on the ideal number of fish. It is not a question of being overwhelmed. Do not throw the fish into the aquarium all at once. If you are about to put the fish in their new home, do not do it all at once, but slowly.

Feeding. Once decided the types of fish that are going to form part of your aquarium, find out about their nutritional needs as well as if it is recommended to give some type of complement to the habitual food or in specific moments like the reproduction. We recommend that you seek advice from your vet on how much to feed and how many times to feed the fish so as not to overfeed them. There are automatic feeders on the market that will feed the animals at those times when you are not at home or going on vacation.

Water heater. If you would like to have tropical fish or fish that need warm water to live, you will have to get a water heater to maintain a correct temperature.

Lighting. The fish should live in an illuminated environment but not receive direct sunlight. We recommend that you buy aquarium lights from a pet store. Don’t forget to turn them off when it’s time to sleep.


It owes its name to its discoverer Mr. Lechmere Guppy. It is one of the most popular fishes because of its beauty and its facility to maintain and reproduce. The males are more varied in color than the females. They have offspring every month.

Tetra fish do not like to live alone

Tetra fish are very colorful, alert and resistant. They do not like to live alone or with few of their species.

Disk fish have characteristic markings

Disco fishes attract attention because of their powerful colors and markings, although they can also be found in a single tone or pure white.


Killifish are easily kept in freshwater aquariums. They are red, blue and orange in color. Males are more colorful than females.


Betta fish were formerly used by the Thai people to make fish fights and were known by the name of Siamese fighting fish. Available in a variety of colors and types of fins, betta fish are very elegant fish. They are easy to care for.


Gourami fish are colorful, active, resistant and easy to care for. They are available in many color combinations, all of which are beautiful. Some gouramis, like the one in the picture, have a kind of whiskers that serve as sensors.


These striped fish owe their name to their smooth movement, like an angel floating in the water. They have no problem with other fish unless they can eat them all at once. Although they can eat dry food, they prefer live ones.


Platy fish are very colorful, active and peaceful, so it is very common to find them in aquariums. They like live food but also eat dry food and vegetables.

These fish like to live in small groups. A curiosity about them is that they eat their own eggs. The male follows the female loaded with eggs and as she deposits them among the plants, he eats them. The male rasbora has a more slender body than the female and the typical triangular mark on the side is sharper on him than on her.

Clownfish, the little fish from the movie looking for Nemo


Amphiprioninae is a subfamily of marine fish of the family Pomacentridae, which contains only the genera Amphiprion and Premnas, whose components are known as clownfish or anemone fish.

Clownfish are characterized by their contrasting and intense colors, red, pink, black, yellow, orange or white. They come from the coral reefs of the Indo-Pacific, and live together with the anemones, theoretically predatory species, from which they obtain protection against possible attackers. In exchange, the clown fish offer the possibility of bringing food closer to the anemone’s mouth, and, with their continuous movement, clean the anemone’s oral disc and tentacles, avoiding bacterial infections. At the same time, adult clownfish defend their host anemones from specialized predatory fish, such as butterflyfish of the Chaetodontidae family.

Easy to obtain, they are simple maintenance fish, so all their varieties are a good choice for aquariums. They are carnivorous species, which need a vegetable contribution in their diet. In their natural environment, clownfish chase their small prey.

The clownfish, which is also called a saltwater fish, is well known all over the world for the intensity of its colors. It is native to the Pacific and Indian Oceans. It is very easy to recognize because its body combines the color orange with various vertical white stripes with a black border.

The length of this species ranges from 8 to 16 centimeters, although generally the females are larger than the males. Its habitat is shallow reefs of warm water. To protect themselves from their predators, such as eels and sharks, they make use of the anemones.

Life expectancy: Clownfish generally have a life expectancy of 15 years. However, if they are found in captivity, they rarely exceed 10 years.
Types: although the vast majority of people consider that there is only one type of clownfish, the truth is that there is a great diversity of clownfish, each with its own characteristics. The most common of all is the one known as Amphiprion Ocellaris.

Clownfish Care

The clownfish is relatively simple to maintain, although it is important to precisely tailor the aquarium to your specific needs.

First of all, it is essential that the aquarium is large because it needs to hold at least 75 liters of water. Although this is a species that does not require as much swimming space as others, it does need a lot of water.

One of the most important aspects of caring for clownfish in an aquarium is to include an anemone. In addition to serving as food, it will also serve as a shelter. If several clownfish live together, each of them needs its own anemone.

In addition, it is very advisable to place plants in the aquarium and to place coral grains. Everything you need to make this space as similar as possible to your home.

Of course, you have to take care of the conditions of the aquarium in relation to the water parameters so that everything is adapted to your specific needs. The water temperature should be between 24 and 26 degrees Celsius. As for the pH, it should be between 8.0 and 8.4. The salinity should be between 1,021 and 1,026. And, finally, the nitrites and nitrates should be less than 0.2 ppm.

The clownfish and its relationship with anemones

On more than one occasion we have asked ourselves what kind of fish is it or what family of fish the famous fish that appears in the famous animated film ‘Finding Nemo’ belongs to. Well, without going any further, the fish that appears in that movie is a ‘clown fish’.

This species of marine animals is characterized by its bright colors, ranging from yellow to orange brown, as we can see in the famous ‘Nemo’. In addition, these fish stand out for their white stripes around their bodies, surrounded by fine black lines.

However, what most characterizes the clown fish is its relationship with anemones, which are marine predators, which have very colorful and poisonous tentacles. Such is the relationship between the clownfish and the anemones that it is convenient to highlight that these fish live, take refuge, reproduce, and even feed surrounded by the anemones.

A very characteristic aspect of this relationship of dependence that we have been talking about, is observed when clownfish feel threatened by other marine species. It is well known that the clownfish is a very colorful fish, so it becomes one of the main victims of other predators, however, living surrounded by anemones, they become their main means of defense.

But not only clownfish are favored by this relationship with the anemones. The oxygenation of the anemone’s tentacles is favored by the clownfish’s swimming around them, which allows for a greater and better flow of water.

To conclude, it is convenient to emphasize that this relationship established by the clownfish and the anemones, is not a relationship of dependence, since both can live without each other. In other words, the clownfish would not die without the presence of the anemones or vice versa, but nevertheless, the life of these two marine species together is much easier. This relationship between the two species is called mutualism.

In Palmitos Park you can observe this special relationship between the clownfish and the anemone, as well as many other species. In our aquarium, the best prepared in Gran Canaria.
