The Gold Rim Tang has been in my 75-gallon reef tank for six months. It’s active and colorful, and hasn’t shown aggression toward other fish. I appreciate the clear size range listed in the description. Feeding is straightforward with high-quality flakes and frozen foods.

This tang is a great addition to a mid-sized reef tank. It’s not overly aggressive, and it maintains a clean appearance. I’ve noticed it spends time near the back wall, which helps with tank balance. Needs a stable environment and regular feeding.

I bought this for my intermediate reef setup. It’s vibrant and active. The size range matches what I expected. I’ve seen it interact with other tangs without conflict. Only issue is it needs a bit of space to swim freely.
