So called because of the extended dorsal-fin rays of mature males, this species should be kept as a group for best effect, despite its relatively large size. It is the most frequently encountered species of its genus, all of which are predominantly silvery-bodied fish with black bands originating in the fork of the caudal fin and extending to varying lengths into the body. Yellow-gold, reddish, or white coloration usually accompanies the bands.
