I bought this triggerfish for my 100-gallon tank. It’s quite aggressive and has been chasing other fish, so I’ve had to keep it in a separate area. It’s active and colorful, but not ideal for a mixed community. Still, it adds a lot of visual interest.
Adam Randall –
The fish arrived healthy and looks vibrant. I’m aware it’s aggressive, and I’ve kept it in a larger tank with no other fish. It’s not a beginner-friendly species, but it’s a striking addition to the display.

After a few weeks, the triggerfish has become a dominant presence in the tank. I’ve had to adjust my tank layout to avoid its territory. It’s bold and lively, and definitely worth the effort if you’re prepared for its behavior.
