==Characteristics== The fishes in the genus ''Helcogramma'' are characterised by the possession of a continuous lateral line which bends down towards the operculum, this lateral line comprises 7–39 tubular pored scales. There are three spines in the first dorsal fin and the anal fin has one spine, the pelvic fin has a single spine and two rays. The head is scaleless and normally the bases of the dorsal and anal fins have a scaleless strip. There are five bones in the joint between the caudal fin and the vertebrae, the hypurals.<ref name =F&E/>
