If you drop in at any good seafood restaurant in Hong Kong (or other places in the Far East) you will often see panther groupers in aquariums. These fish are food, not pets, and the clientele of the restaurant like their fish fresh. For our hobby, panther groupers also make excellent aquarium fish, as long as you are aware of the fact that they live long and grow very large, and they will eat anything they can swallow.
Panthers are very popular because in addition to their hardiness, they are almost comical or clownlike in their appearance. Feeding them is not a problem, and they very quickly adapt to eating pieces of fish, shrimps, clams or the like. Do not feed them freshwater “feeder” goldfish – in fact, don’t feed goldfish to any marine fish, as they are not nutritionally correct for marine fish.
Panthers should usually be kept in a fish only tank, as they will try to eat anything in a reef tank. Make sure that any tankmates are large enough that the panther can’t make a meal out of them. They can be kept with others of their species as long as there is enough room in the tank, and places for them all to hide when they want to.
