Comments:  Though Triggerfish are typically very hardy and easy to feed, they are not all ideal for beginners. These fish are very aggressive and very active, requiring a large aquarium to have enough swimming space. They are territorial and do not get along well with other triggerfish, whether of the same or different species, so it is best to keep just one. This fish may also pick on smaller fish. Triggerfish need to be fed three times a day.

Triggerfish are so named because of the “trigger” spines on the tops and undersides of their bodies. The fish raise these spines when they feel threatened. The spines help the fish lock into whatever hole it is hiding in, to keep predators from being able to pull it out.

These fish are a beautiful addition to a saltwater aquarium. Each species is colorful and their high level of activity makes triggerfish interesting to observe. Their heads are huge, with long pointed snouts and very heavy teeth designed to break open shellfish and crustaceans.

It’s important to furnish the aquarium with plenty of rocks, coral, and other items that form a lot of hiding places. Having many places to hide helps provide security for triggerfish and can lower their level of aggression.
