The Atlantic Blue Tang has been thriving in my 80-gallon tank for over six months. It’s active and peaceful, and doesn’t damage the corals. Feeding is straightforward with algae-based foods. A great addition to a reef setup.

I bought this tang for my reef tank, and it’s been doing well. It’s active and doesn’t nip at other fish. I do need to monitor water parameters closely, but overall it’s a reliable and colorful fish.
