After six months in a 100-gallon reef tank, the clown tang has been active and healthy. It does show aggressive behavior toward smaller fish, so careful tank planning is needed. Feeding it daily with algae wafers keeps it well-fed and active.
David Gray –
This fish is a striking addition to a mature reef setup. It’s active and colorful, though it does chase smaller fish. We’ve had to remove a few small species to maintain harmony. Overall, it’s a great choice for expert aquarists.

We bought this for our 100-gallon tank, and it’s been stable. However, it’s not shy about asserting dominance. We’ve had to monitor its interactions closely. Feeding it twice a day with spirulina and algae wafers works well.
