Info
Norfolkia thomasi is a whitish trifinned blenny with yellow to orange scale margins, six irregular oblique dark brown bands along the upper side that divide on the underside, and an irregular white-edged brown bar below the eye.
Females have narrow, oblique red and white bands on the second and third dorsal fins, while males have brownish-orange dorsal fins.
The species lives in shallow coral reefs and tide pools and is the most widespread of all species.
The genus name "Norfolkia" refers to the finding of the blenny Norfolkia squamiceps around Norfolk Island, which is located in the Pacific Ocean in a triangle between eastern Australia, New Caledonia to the north and New Zealand to the south, but this island belongs to Australia.
Four species are known so far under the genus "Norfolkia":
Norfolkia brachylepis (Schultz, 1960)
Norfolkia squamiceps (McCulloch & Waite, 1916)
Norfolkia thomasi Whitley, 1964
Norfolkia leeuwin Fricke, 1994
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!
