The Lavender Tang has been in my 100-gallon reef tank for six months. It’s active and doesn’t damage corals. Feeds well on algae and small crustaceans. Good for intermediate reef keepers.
Nathan Edmunds –
It’s a bit semi-aggressive, so I made sure to have plenty of hiding spots. It’s healthy and stays active. Works well with my other tangs and corals.

I bought this fish after reading about its reef compatibility. It’s been thriving in my 75-gallon tank. Feeds easily and doesn’t show signs of stress.
