The longfin batfish (Platax teira), also known as the teira batfish or longfin spadefish, is found across the Indo Pacific area. Batfish are commonly found under anchored boats and around mooring chains, seemingly enjoying either having something above them or alongside them. They grow up to 50 centimeters in length and are quite curious fish. Often they come up on a diver to see who or what he is.
They do make their way into the aquarium trade as juveniles, but grow quickly, so a large tank is needed given the size they can grow to. They are omnivores and need a mixed diet. Several can be kept in a tank as they are peaceful and sociable fish and they will form a school and can become tame enough to be hand fed.
