Paradoxodacna piratica is a species of fish in the family Ambassidae, the Asiatic glassfishes. It was described in 1989 and placed in a new monotypic genus of its own, Paradoxodacna.[1] It is native to Indonesia, where it occurs in Sumatra and southern and western Borneo.[2]
This species grows to a length of 9cm (04inches) SL. It has specialized teeth and retrognathous jaws: the upper jaw is longer than the lower. It eats the scales of other fish.[2] This habit inspired its species name, piratica.[1]
This fish lives in tropical streams and rivers.
