Coral blog

One of the most colourful and diverse groups of animals in the sea is definitely reef fish. Its wide range of bright colours and bold patterns is practically unrivalled in the whole underwater kingdom.

And although they may be beautiful to look at, behind each of these designs there is a real function. The red colours look black underwater, which helps fish to stay unnoticed. Stripes allow the fish to camouflage themselves from the coral.

Dotted patterns are used to confuse potential predators. Each fish species cares for its own survival and questions its own performance. Below is a list of the most common fish on coral reefs. Most of these species are suitable for home aquariums.

Incidentally, contrary to popular belief, it is completely acceptable to use the term “fish” to refer to many different species at once. But it is still appropriate to use the word ‘fish’ to refer to members of the same species or members of one group.
