The Yellow-spotted Triggerfish or Blue-and-Gold Triggerfish is another beautiful triggerfish! This is a juvenile specimen since the caudal fin is more rounded.

The tailfin becomes emarginate as the fish matures. Adults will have filaments at the top and the bottom of the caudal fin. Also, the yellow stripes seen in this photo will evolve into spots as the fish gets older.

As with all triggers, to maintain a peaceful tank, be sure to provide the Yellow-spotted Triggerfish or Blue-and-Gold Triggerfish with lots of room and a cave or rocks to retreat into. Also house appropriate fish together that have similar needs and can hold their own. In this case larger protein eaters such as groupers, surgeonfishes, and basses, Some eels and puffers can be appropriate too.
