Additional Information: Make sure your heater has a heater guard, is in your sump, or you have some other means to protect this fish from hiding by the heater and getting burned. Will swim and rest in the upsidedown position. Will eat small fish. The Featherfin color pattern changes quite a lot between its juvenile and adult stage, the juvenile having a body of attractive lines of black and white intervened with irregular spots revealing a “zebra” appearance, only to lose that to a more dull gray/brownish coloration with spots on the body at the stage of adulthood, though keeping a more “lined” appearance at his tail.  The feature that makes this catfish unique is its dorsal fin, that, when raised with all its filaments extended, resembles a moving fan.
