I have 2 tiera bats. They are a pain to keep healthy, often getting clody eyes and ich, they are more brackish fish than salt fish so they handle fresh water dips for 15 minutes plus very well for curing these problems. I keep them with tangs, triggers, and all sorts of community fishes. They just need a deep tank with lots of swiming room, not too much current and no puffers or other fin nippers.
