Triggerfish spp.

These very strange looking fish sure would make a beautiful centre piece in a large marine set-up. They got this name from their ability to anchor them selves in a rocky crevice. They trigger the locking mechanism, by locking the dorsal and second dorsal (that is smaller) fin. Once anchored, the only way to get them is together with the hiding place.
Remember that even though they have small mouth, their powerful teeth are very dangerous and one should pay attention when maintaining the aquarium with a Triggerfish in it. They use their teeth for crushing crustaceans and corals.

Picasso Triggerfish (Rinecanthus aculeatus)

This 25cm long fish is one of the most popular Triggerfish because of its abstract markings. This fish will often produce grunting sounds with it's teeth, if threatened or caught.

Clown Triggerfish (Balistoides conspicillum)

This 50 cm fish is, like most Triggerfish, very territorial.

Red-Tooth Triggerfish (Odonus niger)

This 40 cm long fish is one of the placid Triggerfish one can keep. All Triggerfish need adequate hiding places which should be provided.
