Bought this clown tang for a 100-gallon reef tank. It’s active and colorful, though it does show aggression toward smaller fish. Needs a well-established tank with plenty of space and hiding spots. Feeding it daily with algae wafers and spirulina works well.
Megan Marshall –
The fish looks great and is very active. I had to adjust the tank layout to avoid conflicts with other species. It’s not for beginners, but once the tank is stable, it becomes a great addition to a reef setup.
Alexander Russell –
It’s aggressive and not compatible with small, shy fish. I had to remove a pair of gobies after a few weeks. The tank needs to be large and well-maintained to support this species.
