I’ve kept this female whitespotted boxfish for over a year in a 120-gallon tank. It’s peaceful and doesn’t show aggression. I had to be careful with soft corals, but it’s generally well-behaved. A good choice for experienced reef keepers.

The fish arrived healthy and small, as described. It’s been in my tank for six months. I’ve noticed it’s not active much, but it’s not causing any issues. I’d recommend it only to those with advanced knowledge of reef systems.

This is a beautiful addition to my reef setup. The fish is calm and doesn’t damage any of the corals. I’ve monitored it closely and it hasn’t shown any signs of stress or aggression. Great for a mature reef environment.
