Andrew Walsh –
The Gold Rim Tang has been thriving in my 75-gallon reef tank for six months. It’s active and doesn’t damage corals. Feeding is straightforward with high-quality flakes and frozen foods. Good coloration and steady behavior.
Karen Bower –
This tang is a solid addition to a reef setup. It’s semi-aggressive but doesn’t become overly territorial. Needs a spacious tank and stable water conditions to do well.
Tracey Poole –
I’ve had this fish for three months and it’s very active and healthy. The gold rim is vibrant and it’s not aggressive toward other fish. Only needs occasional feeding and regular water testing.
