The fish is active and colorful. I’ve kept it in a 75-gallon tank with a few corals, and it hasn’t damaged any of them. It’s peaceful and enjoys the open areas of the tank. Only needs moderate feeding and regular water changes.
Jack King –
It’s a beautiful addition to my reef tank. I noticed it occasionally brushes against a soft coral, so I moved it slightly away. Otherwise, it’s calm and doesn’t stress other fish.

Great color and movement. After a few months, it’s grown to about 4 inches and seems healthy. I feed it a mix of frozen and flake food daily. The tank is stable and the fish is thriving.
