Triggerfish:

Triggerfish belong to the Balistidae family, the genera include Balistoides, Melichthys, Pseudobalistes, Xanthichthys, Sufflamen, Odonus, and Rhinecanthus. Triggerfish are found in tropical temperate waters throughout the world inhabiting various areas of the ocean. They feed primarily on bottom dwelling invertebrates, small fish, and some algae. Most Triggerfish are found as individuals or pairs, but some species can be found in schools. Most of these fish reach an average size of six inches in length in an aquarium, and in the wild, some have been known to grow over 30 inches.

Triggerfish get their name from their ability to lock (or trigger) their first dorsal (top) spine vertically, and anchoring themselves into a crevice or hiding place.

Triggerfish are very hardy aquarium specimens that adapt well to captivity if provided with a large tank with plenty of hiding places. Large Triggerfish often become very aggressive toward the its species and other tankmates. Juvenile Triggerfish will grow quickly, and are usually more docile in adulthood than Triggerfish that have matured in the wild.

Triggerfish should be fed live foods such as feeder fish which will often increase the aggression level in an aquarium environment. Feed captive Triggerfish a varied diet that includes primarily meaty foods, supplementing the diet with Spirulina, algae, or dried seaweed.
