Dominic Lewis –
Added this tiny butterflyfish to my 50-gallon reef tank. It’s active and colorful, and it hasn’t shown any aggressive behavior. The fish seems to enjoy the open areas and blends well with the surroundings. Easy to spot due to its distinct oval spots. Very happy with the purchase.
Deirdre Martin –
The fish arrived healthy and looks vibrant. It’s peaceful and doesn’t stress other fish. I’ve been monitoring it for two months and it’s thriving. A good choice for intermediate reef keepers who want a colorful, non-aggressive species.

Perfect addition to my tank. The size is small, so it doesn’t take up much space. It’s active and shows interest in the water flow. No issues with compatibility or behavior so far. Highly recommend for those looking for a calm, attractive fish.
