The fish is active and colorful. I’ve kept it in a 75-gallon tank with some corals and it’s peaceful. Only needs to be monitored for feeding behavior. Good for intermediate reef keepers.
Megan North –
Arrived healthy and has been thriving in my 50-gallon tank. I added some larger fish to avoid aggression, and it’s been calm. Needs a stable environment and consistent feeding.

It’s a nice addition to the tank, but I noticed it occasionally nips at smaller fish. I’ve since removed a few small species. Overall, it’s manageable with proper setup.
