Keoki & Yuko Okano Stender, Hawaii
Info
The blenny Hypsoblennius gentilis occasionally occurs in quiet coastal areas including estuaries, endemic from Monterey Bay south to the Gulf of California / Baja California.
The little guy is brown to greenish, its throat and ventral region are white; a series of dark brown, saddle-like spots are easily seen on its back.
Along the side of the body, at the level of the pectoral fin base, is a horizontal row of white spots.
The dorsal fin shows a red spot on the anterior side.
Adult males are easily recognized by a red bar running across the throat, the bar is most pronounced during the courtship and breeding seasons.
Hypsoblennius gentilis is a territorial species.
Hypsoblennius gentilis often becomes prey for seabirds, which prey on the fish in shallow water zones.
Synonym: Blennius gentilis Girard, 1854
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!
