Psilogobius prolatus Watson & Lachner, 1985
Psilogobius prolatus was already described in 1985, but thanks to Joe DeVroe we now also have a colour photo of the small sentinel goby.
The sentinel goby lives in sheltered bays and lagoons and is also found in estuaries with low salinity. It is also found in sand and gravel bottoms at depths of 1-20 metres. Which crayfish the goby is associated with needs to be added.
A very common goby in Australia and around Cocos Keeling Island, unfortunately we have no information on keeping it in a marine aquarium.
Description: Characterised by a pale grey to brownish body colour with five large, egg-shaped dark brown spots on the side of the body; front part of the body with narrow white bars; upper half of the head and body with brown spots and small blue spots; blue stripes aligned with the fin rays on the middle fins; elongated and thread-like third dorsal spine; the ventral fins are connected to form an elongated, cup-like disc. Small ctenoid scales cover the body; head without scales, except for a small patch of ctenoid scales over the gill cover.
Psilogobius prolatus there is a pronounced sexual dimorphism. In addition to the genital papilla, males have longer fins, longer filamentous first dorsal fin spines, longer upper jaws than females and differ in colouration.
Psilogobius prolatus differs from Psilogobius mainlandi by a dark pigmentation of the upper jaw, the AITO sensory pore that is normally present, a small patch of tiny scales on the gill cover, less numerous pectoral fin rays (modal 15), longer dorsal, anal and caudal fins, a longer upper jaw and certain sexually dichromatic markings or bars.
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!
