The butterflyfish is vibrant and active in my 55-gallon tank. It’s peaceful and doesn’t bother other fish. I appreciate that it’s reef-safe and fits well in a mixed community. Easy to spot and adds a lot of visual appeal.

It’s a beautiful addition to my reef tank. I’ve had it for three months and it’s still active and healthy. The fish is calm and doesn’t stress other inhabitants. Only needed a bit of hiding space initially.

Great choice for intermediate reef keepers. The fish is colorful and stays in one area without chasing others. It’s easy to maintain and has adapted well to the tank conditions.
