Info
Trinorfolkia clarkei is a variable grey to brown or orange trifinned fish with usually seven darker bars along the dorsum that are divided ventrally, a prominent bar below the eye that is curved backwards, and often a large black spot on the first dorsal fin.
Its colour is extremely variable and thus well adapted to the habitat, ranging from grey to brown or orange, usually with seven evenly distributed darker bars dorsally, bars divided ventrally; usually with a very pronounced bar below the eyes, curving backwards; first dorsal fin often with a large black spot; dorsal and anal fins with wavy lines or evenly pale yellow to deep orange.
The similar three-finned blennyTrinorfolkia incisa has deeply incised or notched membranes on the first dorsal fin.
Trinorfolkia cristata, a three-fin blenny found in South Australia, has a very high first dorsal fin.
Trinorfolkia clarkei was named after the type locality, Clarke Island in Bass Strait, Tasmania.

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!
