Info
Priolepis cyanocephala is a yellowish goby with a bluish head, distinct scale margins, four vertical bands on the head and no bands on the body.
The blue-headed reef goby differs from other Priolepis species in having a reduced transverse papilla, second dorsal fin rays, a largely naked dorsal fin, and a head with vertical bands but no bands on the body.
Species of the genus Priolepis form monogamous pairs and are capable of bidirectional sex change.
In laboratory experiments with female-female pairs, the larger individual changed sex to the male, and in male-male pairs, the smaller one changed to the female. The gonads of these species simultaneously formed ovarian and testicular portions with an accessory gonad structure.
The species name "cyanocephala" is composed of the Greek "cyano" (= blue) and "cephalus2 (= head) and refers to the blue head of this species.
Very special thanks for the first photo of Priolepis cyanocephala to Rudie H. Kuiter, Australia.
Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
