Crystallogobius linearis (Düben, 1845)
Distribution: Eastern Atlantic: Lofotens, Norway, to Gibraltar. Also known from the Mediterranean Sea. Eastern Central Atlantic: Madeira Island .
Biology: This occasionally territorial species occurs in coastal waters, over shell, sand, or mud bottoms; males bottom-living during breeding season. Feed on zooplankton.
Spawning takes place when 1 year old. Adults die afterwards. Eggs are laid in the empty tube-worms and are guarded by the male.
Eggs are pear-shaped.
Synonymised names:
Crystallogobius nilssonii (Düben & Koren, 1846)
Gobius linearis Düben, 1845
Gobius nilssonii Düben & Koren, 1846
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!
