Descriptions and further reading
Family description (Cirrhitidae)

Hawkfish stay still and wait for food most of the time, they are therefore suitable for smaller aquaria.

One must be aware that Hawkfishes can be very aggressive.

Very aggressive genera
The very aggressive species will sometimes attack many different types of fish, even the ones that are larger than themselves.

Cirrhitops
Cirrhitus
Paracirrhtes

Semi aggressive genera
The semi aggressive species are most threatening towards fish whose behaviour mimcks their own, and fish which are introduced after they have settled in.

Cirrhitichthys

Less aggressive genera
The less aggressive species are rarely threatening towards fish that which do not resemble them.

Cyprinocirrhites
Neocirrhites
Oxycirrhites


Larger Hawkfishes might eat small fish, shrimps etc. in the aquarium. Species of the Cyprinocirrhites and Neocirrhites genera are least likely to eat shrimps etc.

Hawkfish do not place many demands on their surroundings or water quality, as they are fairly hardy.

It is possible to keep several Hawkfish together, but sometimes they will suddenly begin to fight after some time in the aquarium.
This may be due to them changing gender so one can end up with two males.
