I’ve had this triggerfish for six months in a 75-gallon tank. It’s active and curious, and has not damaged any corals. The fish is a bit territorial, so I made sure to keep it with larger, calm species. It’s a great addition to a reef setup with proper space and hiding spots.

The fish arrived healthy and has been adjusting well. It’s not overly aggressive, but it does defend its area. I’ve added some rock structures to give it space. It’s a unique and visually interesting species.

This is one of the rare triggerfish I’ve seen in a store. It’s active and colorful. I keep it in a well-established reef tank with plenty of live rock. It’s not aggressive toward other fish, just cautious around new additions.
