BALISTIDAE (TRIGGERS)

Triggers live in reef areas where the water is in constant movement, so you must plan a large aquarium
for them (at least 400 liters) with highly agitated and well-oxygenated water. Their jaws and teeth
allow them to graze on coral, crabs, and mollusks. In captivity they accept animal food, such as small mollusks (cockles, mussels), complete with their shells. They are fairly aggressive and must be kept singly, away from small fish and invertebrates. One of the distinguishing features of this family of marine fish is its ability to stick out the first spoke of its dorsal fin, and then block it with the second one (explaining their alternative name of crossbowmen).
