William Brown –
The Melon Butterflyfish is active and colorful. It adapted well to our 55-gallon tank after a few weeks. It doesn’t bother other fish and stays near the coral. Very happy with the purchase.
Dylan Rees –
We added this fish to our reef tank and it has been peaceful. It’s a striking color and stays in the middle of the tank. Needs a stable environment, but overall a good addition.
Joan Martin –
The fish arrived healthy and was easy to acclimate. It has been in the tank for two months and shows no signs of stress. The size is as described, and it’s a beautiful addition to the reef.
