Blue body; dark/black hook shaped marking between eye and tail; tail is yellow bordered in black. Since being cast as “Dory” in the movie “Finding Nemo”, Blue Tangs are disappearing from their native reefs from increasing hobby demand. Captive-bred Blue Tangs have been available from Biota, but until they are aquacultured regularly, they will remain on the Bad Fish list.
