I bought this fish for my 80-gallon tank. It’s active and colorful, but I had to keep it isolated from smaller fish. It’s aggressive, so I made sure to place it in a corner with plenty of hiding spots. After a few weeks, it settled in and started feeding well. Great addition to a larger tank with compatible species.

The Red Sea triggerfish looks stunning in the tank. I’ve had it for two months now and it’s still active. I noticed it’s not compatible with shrimp or small corals, so I removed those. It does need a large tank and a lot of space to move around. Overall, a bold and impressive fish for experienced aquarists.

It arrived healthy and seems to be adjusting well. I’m cautious about its aggression and have kept it in a separate section. It’s not for beginners. The tank size is a must, and I’m glad I followed the minimum size recommendation.
