Orange-lined TriggerfishFamily: BalistidaeBalistapus undulatus
Even though he's a beauty, this guy has the reputation of being the most aggressive triggerfish! Which means the Undulate Triggerfish or Orange-lined Triggerfish may be the most aggressive fish, period! Actually they are okay when they are small, but get cantankerous as they get older.
Make sure you have a large aquarium or not very many other fish. Give it lots of room and a cave or rocks to retreat into.
The Undulate Triggerfish or Orange-lined Triggerfish can be worth keeping since it is lively, colorful, and will grow to be a nice pet, taking food from the owners' hand! Watch your fingers though, the teeth are very sharp and can deliver a painful bite.
