When and how should feed be administered?

We recommend feeding your tropical fish two or three times a day, but always in small amounts.

Only what your fish consume in two or, at most, five minutes.

As far as possible, spread the food evenly over the surface.

Use a spoon reserved for this purpose to supply the food. This will make it easier for you to always serve the same amount. In addition, the aroma and quality of the food will remain unchanged

excessive feeding

If after an hour the food is still at the bottom, it is a sign that you have fed too much.
remove food residues with the sera bottom vacuum cleaner
· if possible, introduce fish that forage on the bottom, for example coridoras (minimum 5 fish of each type).

new food

If you give your fish an unknown food, they are often suspicious; what they do is check if an enemy has entered. But after a little time the fish will have become accustomed to the food.


Pet Planet wants to go further than any pet store that sells fish food and therefore gives you some advice that we hope will be practical when choosing the best food for your fish:

The food for the fish

Due to the growing demand for aquariums and fish in the home, I have improved and increased the number of food / fish food that we can find in pet stores. In specialized pet stores we will mainly find food/dry food for fish, although frozen food/food is becoming more and more fashionable and freeze-dried for fish , even though they are harder to find and more expensive.

Dry fish food : This is the most used type of fish food, due to its ease of availability and because it practically meets all the nutritional needs of fish. Within the dry food for fish we can distinguish: flakes, granules, lumps and tablets. Before selecting a food, consider whether your fish are hot or cold water, sinceThere is a type of food for each of these fish.

There are live foods for fish, this type of fish food is difficult to find or acquire, such as Artemia salada,  Cyclops, Daphnia, Drosophila, Mealworms, Earthworms (in fishing stores), etc.

Finally, to mention homemade food for fish, we have non-vegetable food for fish: The most normal are mussels, prawns, prawns, clams, etc. Cook them until they open. They can be frozen and thawed depending on what is needed. And to vegetable food for fish: the most common is lettuce, chard, etc. Normally easy to eat, but always somewhat boiled to eliminate toxins.

All the advice given is generic, therefore we advise you to get information based on the species of fish, since it can change substantially.
