i can only think of the hippo blue tang but i dont want another tang since i have a purple and sailfin already. are there any other bright blue fish that is reef safe and wont fight with my tangs?
my tank is 100 gallons, running for over 2 years now. i have two tangs, a orchid dottyback, a pair of wheeler gobies, one flame angel and a lot of corals and inverts.
