This one is a juvenile, which is the best age to bring one home: young flagfins settle in and take prepared foods far more readily than adults. As it grows, the dark eye bar and the black spot near the back of the dorsal fin fade, and it develops the small dark forehead spot that gives the species its \"three spot\" name. Care level is intermediate and temperament is semi-aggressive.
