William Lambert –
Got this triggerfish for my 55-gallon reef tank. It’s active and colorful, though it does show aggression toward smaller fish. I’ve kept it separate from shrimp and small wrasses. It’s a striking addition to the display and fits the beginner level as described.
Abigail Wilson –
The fish arrived healthy and looks vibrant. I followed the care guide and maintained a large tank with plenty of hiding spots. It’s not shy and shows strong coloration. I’m happy with the purchase despite its aggressive behavior.
Stephen Pullman –
It’s a bold fish and not for small tanks. I had to reposition it after a few weeks to avoid conflicts. Still, it’s a unique and eye-catching species that adds visual interest to the tank.
