Bought this triggerfish for my 80-gallon reef tank. It’s been two months and it’s active but not causing any issues. I noticed it occasionally bumps into soft corals, but nothing serious. Good for intermediate reef setups.

The fish arrived healthy and seems to adapt well. I’m cautious about its behavior around smaller polyps, but it hasn’t damaged anything yet. Needs a spacious tank, which I have.

This is a rare addition to my tank. It’s active and curious, and it doesn’t eat the corals. I appreciate the care level being intermediate—easy to manage with proper tank size.
