Blue Damselfish

BAD Fish
Blue-Damselfish-1

Blue body and fins; black band from snout to eye; females with black spot on rear dorsal fin; males with scattered tiny yellow/white spots and yellow/orange tail.  Commercial level captive-breeding is possible. Trade incentives to do so are hindered by a number of market factors favoring wild-caught. It is likely that many Blue Damselfish are captured illegally with cyanide, yet they remain among the top 3 marine aquarium fish imported into the U.S.
