The compatibility of fish according to their species

by Akua Design 19 Feb 2023

When setting up an aquarium, it is important to take into account the compatibility of fish according to their species. This will ensure a healthy and harmonious environment for the fish in the aquarium.

Factors to consider

There are various factors to consider when determining the compatibility of fish in an aquarium, including:

  • The size of the fish: It is important to consider the size of the fish, as larger fish can easily swallow smaller fish.
  • Fish behavior: some fish have territorial or aggressive behaviors, while others are more calm and peaceful.
  • Water needs: fish have different water needs, especially in terms of pH, temperature and salinity. It is important to select species of fish that have similar needs.
  • The diet: some fish are carnivorous, others are herbivorous or omnivorous. It is important to select species that have compatible diets.

Common Fish Associations

There are different associations of fish that are common in aquariums. Here are a few :

Fish Compatibility with
Guppy Neon Tetra, Corydoras, Platys, Mollys
Scalar Corydoras, Discus, Angelfish
Sumatran Barb Red Nose Tetra, Danios, Rasboras

However, it is important to note that each fish is unique and compatibility cannot be 100% guaranteed. It is therefore recommended to research each species of fish before placing them in a common aquarium.

Conclusion

By following compatibility factors and common fish associations, it is possible to create a healthy and harmonious environment for fish in the aquarium. It is important to take the time to research and plan the aquarium carefully to ensure fish compatibility and long-term well-being.

Finally, remember that fish compatibility is not just limited to fish species. It is also important to take into account the other animals in the aquarium, apart from the compatibility of fish species, it is also crucial to take into account the presence of other animals in the aquarium. Some fish can be aggressive towards other fish, but they can also be aggressive towards other animals, such as shrimps, snails and crabs. It is therefore important to know which species of fish can coexist peacefully with other animals and which are more likely to attack them.

In general, larger fish tend to be more aggressive towards smaller animals, while they are less likely to be disturbed by fish of their own size. Predatory fish, like eels and top predators like bettas, should not be kept with shrimp or snails as they will regard them as prey.

Other species of fish, such as cichlids, tend to be territorial and may attack other fish that enter their space. It is therefore important to know how much territorial space each species requires and to plan accordingly. More territorial fish need ample room to move around and hide, which can help minimize conflict.

When selecting fish for an aquarium, it is important to consider their temperament and compatibility with other species. It is also essential not to overload the aquarium in terms of the quantity of fish or their size, which can lead to stress and restlessness, as well as conflicts between fish.

In short, the compatibility of fish according to their species is a crucial element to take into account to ensure the health and well-being of fish and other animals in the aquarium. By following these tips and selecting fish that live together peacefully, it is possible to create a harmonious and healthy environment for everyone in the aquarium.
