The Round Batfish is a large batfish, which is only suitable for the largest home aquariums. As juveniles they've extremely elongate vertical fins and are reddish brown, a bit resembling a dead leaf. And this is also how they avoid predators, lying on their side, rocking back and forward by the current, hoping a predator thinks it's just a leaf. As adults they're more rouded and silvery with dark broad vertical bands. In nature juveniles live close to the mangrove forests, but adults are usually seen in singly, in small groups or occcasionally in a large group in deeper water. Often associated with large sandy areas and shipwrecks.
A few things to think about before purchasing a batfish are that wild caught fish can be hard to wean to food and might be susceptible to white spot. Once adapted to captivity they usually pose no problems anymore.They can eat small fish and shrimps however, so make sure to pick their tankmates with care. Corals are generally left alone but some might harass anemones.
The body of Platax orbicularis is almost disc-shaped, and very thin. Its tail, about 20% of the body length. The small reddish-brown juveniles resemble floating leaves drifting amongst flotsam at the surface.
