I bought this triggerfish for my 150-gallon tank. It’s active and bold, which is exactly what I wanted. It’s not aggressive toward other fish, though it does defend its territory. Feeding is straightforward with a diet of crustaceans and algae. Needs a large tank, but it’s a great addition to a well-maintained setup.

The fish arrived healthy and quickly settled into the tank. It’s quite striking in color and has a strong presence. I’ve kept it with a few other species, and it doesn’t attack them directly. Just make sure the tank is large enough and has plenty of hiding spots.
Zoe Wright –
It’s aggressive and not suitable for smaller tanks. I had to upgrade my tank size to 150 gallons. It does eat a lot and needs a varied diet. Works well in a spacious, stable environment.
