The Pinnatus Batfish, Platax pinnatus, will display a dramatic change in appearance while in different stages of life. As a juvenile it displays a dark brown/black colored body outlined in vivid orange while as an adult the dark black color begins to fade. They are hardy fish that are very peaceful and can be kept singly, or in larger tanks as a pair, or a small school and should also be kept with other larger peaceful fish.

They are not reef safe however since they will consume smaller fish, invertebrates, corals and anemones present in the tank. Diet should include a variety of live feeder marine fish and feeder shrimp and frozen chopped meaty preparations like crab, krill, squid, and shrimp 2-3 times daily.
