Description

The Mirror Butterflyfish (Chaetodon Speculum), is a species of Butterflyfish found in the Indo-Pacific region from Indonesia to Japan and south to the Great Barrier Reef and Papua New Guinea. The species has also been reported from Madagascar, Mauritius and Réunion. The Mirror Butterflyfish grows to a maximum of 7″ inches in length. The body color is a bright to orange-yellow with a big black blotch below the dorsal fin and a vertical black bar running through the eye.

Like the other Butterflyfishes with angular yellow bodies with black eye-stripes and a single differently-colored patch (except in the quite basal Blue-Lashed Butterflyfish), the Mirror Butterflyfish belongs in the subgenus Tetrachaetodon. Among this group it seems to be particularly close to the Zanzibar Butterflyfish which has a smaller black blotch and traces of horizontal stripes on the flanks.
