Info
Cryptocentroides gobioides is a slender, olive-green goby with a speckled back, many alternating bright blue and orange bars along the side, blue spots on the head, two rows of dark pink stripes on the dorsal fin, and reddish anal fin rays with blue membranes.
Males may be darker than females. As the colloquial English name suggests, this species has a pronounced crest on the top of the head.
The goby inhabits shallow muddy and rocky areas as well as oyster and mussel beds, often in the intertidal zone in estuaries, bays, and harbors.
It is usually found in estuarine and brackish waters, especially oyster beds, and hides in holes and under rocks when threatened.
Synonyms:
Cristatogobius gobioides (Ogilby, 1886)
Gobius cristatus MacLeay, 1881
Gobius gobioides Ogilby, 1886
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!
