The Gold Rim Tang arrived healthy and active. It has adapted well to our 100-gallon reef tank. We’ve noticed it’s not overly aggressive and doesn’t damage corals. A good choice for intermediate reef keepers.

We’ve had this tang for three months now. It’s active and curious, and it doesn’t seem to harm the reef. A bit of caution is needed with soft corals, but overall it’s a stable addition.

Great fish for a reef setup. It’s grown steadily and shows no signs of aggression. The size is manageable and it’s a nice color contrast in the tank.
