Added a male Blue Throat Triggerfish to my 75-gallon reef tank. It has been active and peaceful, showing no aggression toward corals or other fish. The fish is colorful and adds a nice visual element to the tank. Requires regular monitoring of tank conditions, but overall a good fit for a reef setup.

The fish arrived healthy and has adapted well to the tank. It’s semi-aggressive but doesn’t harm corals. I’ve noticed it spends time near the rockwork, which is a good sign. Needs a stable environment and consistent feeding.

Great addition to my reef tank. The Blue Throat Triggerfish is active and curious. It doesn’t damage corals and has become a regular part of the tank’s ecosystem. Only requires moderate attention and a large tank size.
