Heteropriacanthus
Heteropriacanthus, the glasseyes or glass bigeyes, are a genus of the bigeye family found in all tropical seas around the world. It occasionally makes its way into the aquarium trade. It grows to a size of in total length.
The glasseyes has been classified in a single species, Heteropriacanthus cruentatus, but recent morphological and genetic analysis indicates that glasseyes may be better divided into three species: Heteropriacanthus cruentatus, H. fulgens, and H. carolinus. H.cruentatus can differentiated from the rest of its genus by looking at its caudal and anal fin in which is distinct in colour.
