Phil Mackenzie –
I’ve had this triggerfish for six months in a 75-gallon tank. It’s active and colorful, though it does need space and a secure setup. It doesn’t eat corals, which is good. I keep a few larger fish around it, and it’s not overly aggressive with them. A solid choice for a reef tank with experience.
Amelia Forsyth –
The fish arrived healthy and looks vibrant. It’s been a few months now and still active. I appreciate that it’s reef compatible. I’ve had to be careful with tank mates, but it’s not destructive. A great addition to a well-established tank.

It’s aggressive and needs a lot of space. I didn’t expect it to be this territorial. I’ve had to keep it in a larger tank and avoid placing it near smaller fish. Still, it’s visually striking and adds a lot of color.
