Neil Dowd –
Got this triggerfish for my 150-gallon tank. It’s active and colorful, though it does show aggression toward smaller fish. I’ve kept it separate from shrimp and snails. Water parameters are stable, and it’s adapted well after a few weeks.
Molly Campbell –
The fish arrived healthy and looks vibrant. I’m cautious about its behavior, especially around tank mates. It’s not ideal for a mixed reef setup. Still, it’s a striking addition to a large tank.
Thomas Nash –
Perfect for a beginner with a large tank. The fish is active and shows good health. I’ve maintained a consistent water temperature and salinity. It’s not aggressive toward other fish in the tank, as long as they’re larger and not hiding.
