Parablennius rouxi (Cocco, 1833)
Distribution:
Northeast Atlantic: off Portugal. Also known from the northern Mediterranean.
Occurs in the shallow littoral zone to the zone beyond the influence of water movements, over light rocks or pebbles without algal cover and on secondary hard bottoms of coralligenous origin.
Feeds on periphyton, harpacticoids and algae.
Males inhabit narrow piddock holes; they court by nodding, jumping out of hole and back again and swimming in a vertical position.
Rivals are threatened by yawning, lateral display and circling, and are attacked by ramming and biting.
Oviparous.
Reproduction takes place from May to July. Attracted females spawn in resident hole of a males which guards eggs from several families. Eggs are demersal and adhesive.
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!
