Acanthurus triostegus (Linnaeus, 1758)
Convict surgeonfish often assemble in large schools consisting of up to 1000 specimen. It can be found above hard substrates in depths up to 90 m.
It is a peaceful species. Accustomed to captivity as juvenile, it is a very beautiful fish for medium- and large-sized tanks. A very good algae eater.
Unfortunately often large, almost grown-up specimen are being imported which have difficulties in acclimatizing.
Convict surgeonfish grow very fast.

The surgeonfishes (Acanthuridae), popular in marine aquaristics, are also called surgeonfishes.
They have horn-like blades in front of the tail root, they use as mainly defensive weapon (defense) against predators, but this sharp weapon is also used in fights among themselves.
Deep cuts in the body of opponents can cause permanent injuries, but often death occurs immediately.
If surgeonfishes are to be kept in pairs in an aquarium, fights between the fishes can be the order of the day, we could observe this several times with the very popular Hawaiian surgeonfish (Zebrasoma flavescens).
The scalpel-like blades can cause deep cuts, this is also true for the careless aquarist who wants to touch or catch the fish with unprotected hands.
Another problem can occur if one wants to catch surgeonfish with a landing net and transfer them after catching, the horn blade can easily get caught in the net.
Caution: Careless handling of the animal can cause deep cuts!
