Victoria Wallace –
I’ve kept this triggerfish for six months in a 55-gallon tank. It’s active and territorial, so I removed a few small fish that were too vulnerable. The algae control is impressive. Needs a large tank and careful management, but it’s a great addition for experienced reef keepers.
Rebecca Dowd –
It’s aggressive and not suitable for beginners. I had to rearrange the tank layout to give it space. It eats algae well but can be a challenge to manage with other fish. Good for intermediate hobbyists who understand its behavior.

The fish arrived healthy and has been thriving. I’ve maintained a stable environment with plenty of hiding spots. It’s active and helps keep the tank clean. Definitely not for small tanks or shy fish.
