Info
This goby has been endowed by Mother Nature with a potent neurotoxin, tetrodotoxin, this toxin is also found in puffer fish, blue ringed octopus and other invertebrates such as various crustaceans, mollusks and starfish.
Therefore, at least the consumption of this fish is warned against.
The goby occurs solitary on sandy and slimy bottoms around inner reefs in moderate depths up to about 10 meters.
Quite often the goby is also found in mangroves, estuaries and even in freshwater.

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!
