Redtail butterflyfish

It can be found in reefs of the Indo-west Pacific region: from the Persian Gulf and Maldives to Japan, the Philippines, and Indonesia.[4][5] The mailed butterflyfish (C. reticulatus) is a near-match of C. collare in appearance, save for a less brown hue and light blue instead of red in its black-based tail.However DNA sequence and osteology data overwhelmingly agree that C. reticulatus belongs to the subgenus called "Citharoedus" (a name preoccupied by a mollusc genus).This contains fish like the scrawled butterflyfish (C. meyeri), similar in shape and size but with a "finger-painted" pattern of a few prominent and uneven lines on a light silvery background.These butterfly fish have a viable tolerance to chelated and ionic copper medications, and thus can be kept in quarantine systems that employ these anti-parasitic techniques.
