I bought this Pink Tail Triggerfish for my 75-gallon reef tank. It’s been two months and it’s active but not aggressive. I’ve noticed it occasionally nudges soft corals, so I’ve rearranged the layout to avoid those areas. It’s a good beginner fish with a vibrant color.

The fish arrived healthy and fits well in my tank. It’s not overly active, but it does show interest in the rockwork. I keep it separate from small shrimp and snails. Overall, a solid addition to a beginner reef setup.

I was worried about compatibility, but after reading the care notes, I felt confident. The fish has adapted well and looks great. I’ve made sure to keep it in a tank with hard corals and no soft ones. It’s a beautiful and manageable species.
