COMPATIBILITY BETWEEN INVERTEBRATES AND MARINE FISH
 

COMPATIBILITY BETWEEN INVERTEBRATES AND MARINE FISH

Invertebrates cannot cohabit with just any fish, for a number of reasons. The first is that they are liable to become prey for carnivorous fish. Coelenterates are completely incompatible with angelfish (Pomacanthids), for example. Secondly, some lively and active fish, of over 10-15 cm in length, can jostle and disturb invertebrates in the aquarium.

Furthermore, the bigger and more active a fish, the more it excretes nitrogenous substances, leading to the accumulation of nitrates (NO3-), which are harmful to invertebrates. It is therefore best to avoid the presence of this type of fish. Too many fish produce the same result and the same degree of harm for invertebrates.

Finally, there is another problem when a sick fish has to be treated, particularly with substances containing metals, which are toxic for most invertebrates. Remember that it is always preferable to nurse a fish in a hospital aquarium.
