Types of Food For Aquarium Fish

The food for aquarium fish is one of the recurring doubts among those who start in the aquarium. This wakefulness is logical for multiple reasons. The main one: that an aquarium is made up of different species of fish. A variety that largely marks the feeding needs of each one. Although at first glance we may think that aquarium fish food is the same for everyone, the reality is that it is not. There are species with specific needs that, in order to nourish themselves properly, demand special attention. And no: we cannot ignore these demands as they can compromise your health.

Food For Aquarium Fish

It is clear that, in any species, food is vital for its well-being . But in the case of these animals, we have to be even more rigorous. Aquarium fish food is the key to strengthening your immune system and ensuring a full life. A poorly fed fish will fall ill at dizzying speed, compromising both its life and even that of the other members of the aquarium. Reason enough to be extremely careful in this regard.

But as important as choosing the necessary aquarium fish food for each species is to do it in the correct format. And it is that the fish’s need for nutrients means that, far from giving them a single meal, we have to administer different types of food that complement each other . Let no one be overwhelmed! The idea is precisely to remove fear from this vital and routine task. And, for this, nothing like knowing more about the options we have available.

5 Types of Food For Aquarium Fishes 

Although we are going to look at the different types of aquarium fish food , there are some considerations to take into account before going into detail. The first one: the age of our animals . The size of the mouth of a fry is not the same as that of an adult fish. A good reason for us to be careful in this regard.

Aquarium fish food needs

Besides this and before choosing a certain food for aquarium fish, we have to thoroughly investigate the characteristics  of each species of fish. The reason is simple. There are herbivorous, carnivorous and omnivorous fish. And, although we may believe that nothing happens to alter this diet, it is not. Herbivorous fish have a longer digestive tract than a carnivore. For this reason and in case of offering a diet low in fiber, we can cause intestinal problems. And, conversely, it is also problematic. A fiber-fed carnivorous fish will not have the energy supply it needs to live in full vitality.

We leave one last consideration for the end. And it is none other than the  feeding habits of each fish . Because, while there are fish that eat on the surface, others do so naturally at the bottom of the aquarium. And contemplating this aspect is as important as choosing the correct composition of the diet of our fish.

So let’s see what options we have when it comes to food for aquarium fish.

1. Dry food, the most common food for aquarium fish

Food For Aquarium Fish

It is the most widely used fish food for a number of reasons. On the one hand, for its incredible versatility of presentations. We can have it in flakes, granules or flakes. But it is not the only thing in which dry food is versatile. It is also in its nutritional proposal, since we can find food for aquarium fish in this format for both carnivores and herbivores.

Dry aquarium fish food is the most common. 

In addition to this, the dry fish food is enriched in vitamins and nutrients . One last detail that makes this food an important part of a balanced diet. But be careful: dry food should not make up 100% of the diet of any fish.

2. Lyophilized food

Lyophilized food

In appearance, freeze-dried food is very similar to dry food. But it is only appearance because this type of food for aquarium fish has a substantial difference: its composition. The genius of freeze-dried foods is that they allow us to have certain foods rich in nutrients .

Freeze-dried aquarium fish food concentrates raw materials, vitamins and minerals.

And it is not that we cannot dispense them to our fish in another way, because we could do it fresh or raw. However, if we opt for freeze-dried food, we will be sure that we are administering a diet free of parasites and pathogens . And with another plus: thanks to the drying process of this type of food, the nutrients remain despite being manipulated.

3. Non-living fresh food

Non-living fresh food

Many of the carnivorous fish of tropical origin demand fresh food in their diet. We refer to prawns, mussels or even chicken or animal entrails. Although the administration of this type of food must be punctual , it is necessary to be cautious. Not all fish demand or tolerate fresh food. A good reason, yes we insist!, To know for sure the feeding routines of our fish.

Even though this aquarium fish food may seem healthy, watch out. Introducing fresh food into the aquarium can be dangerous for many reasons . On the one hand, because we can introduce a parasite or pathogen that ruins our fish colony. On the other, because its presence uncontrolled the parameters of the water.

4. Live food, the food for aquarium fish that provides the most nutrients

Live food

Let’s not fool ourselves. In a natural environment, fish that are not purely herbivores feed on live animals. The most common snacks are water fleas or daphnia, mosquito larvae, small worms called tubifex, and shrimp.

And yes: it is clear that its nutritional contribution is infinitely greater than any other type of food for aquarium fish. But, again, their presence in the aquarium can compromise your health. They can be a source of pathogens and parasites.

5. Frozen food

Live food

The perfect alternative to be able to give our fish live food guaranteeing safety. The same snacks that we have mentioned are usually available frozen. And the only precaution we will have to take with them is when administering them to our fish. With yet another attraction: that, despite being frozen, they retain a good part of those nutrients that make them healthy delicacies for fish.

To do it correctly, the ideal is to remove a little water from the aquarium and put the different crustaceans and worms in it to thaw. When they are tempered and completely thawed, we can add them to the aquarium so they can enjoy them.
