The Golden Butterflyfish is vibrant and active in my 100-gallon tank. I’ve kept it for six months and it’s peaceful, though I’ve had to monitor it closely around soft corals. It’s a beautiful addition to a reef setup with proper care.
Adam Rees –
It arrived healthy and has been thriving in my tank. I noticed it occasionally nibbles on a soft coral, so I’ve repositioned it to avoid contact. Overall, it’s a striking fish and fits well in the community.
