I bought this butterflyfish for my 50-gallon reef tank. It’s been two months and it’s very active and peaceful. It doesn’t eat much and seems to adapt well. I appreciate the clear instructions on compatibility and care.

The fish arrived healthy and looks vibrant. I made sure to keep the tank well-maintained and avoid placing it near delicate corals. It’s a good choice for a beginner with a reef setup.
