For the first time ever we were able to import this interesting freshwater-goby from Vietnam. The species and the genus have been described only in 2003. Papuligobius uniporus attains a maximum length of about 7.5 cm. There exists only one other species in the genus, namely P. ocellatus, which has been described already in 1937, but which obviously never appeared in the aquarium hobby. The easiest way to distinguish the two species is the coloration of the caudal fin, which is striped in P. ocellatus, and the coloration of the basis of the pectoral fin. Here P. uniporus has three eye-spots, P. ocellatus only one.
Against conspecifics P. uniporus can be a bit quarrelsome. The species has the ability to change the coloration drastically. Most often they look almost deep black, but they can also show a light stripe or a marbled pattern.
These gobies have no special demands regarding water chemistry. They feed readily on any type of frozen of life food that fits the mouth.
