Info
We like to thank Dr. Glen Whisson,Aqua Research and Monitoring Services, Australia and Dr. Julian Finn / Museum Victoria, Australia, for the first four photos of Nesogobius pulchellus.
Nesogobius pulchellus is a resident of sandy areas near seagrass beds, rocky reefs in bays and estuaries.
In the small sand goby, the anterior part of the first dorsal fin is dark and high, especially high and tapering in males. Males also have a dark head and dark/black anal fin (which is unpigmented in females) and signal their mood with their high dorsal fin, among other features. The second dorsal fin and the anal fin start with a spine.
The body of the goby is relatively dark, grayish brown and mottled with reddish spots that form stripes on the dorsal fin.A thin brown bar runs from the eye to the middle of the jaw, which is more evident in juveniles.On both sides of the body are well visible with 5 - 8 dark brown spots, below the sides of the body is a thin, interrupted silver stripeIn front of the tail is a broad v-shaped brown bar.
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!
