Size 200mm or 7.9" SL. Find near, nearer or same sized spp.
IdentificationDistinguished from other species in the genera by its concave head that rises ahead of the dorsal fin, giving the fish a hump back appearance. The eyes are positioned closer to the tip of the snout than in other related species.
Appearance can vary from a mottled light grey, typically seen in younger specimens, to smooth dark colour. A light gold / tan hue may be apparent in some specimens, this may be influenced by environmental factors.

FeedingAccepts most prepared and live or frozen foods in captivity. Natural diet predominantly aquatic insects (midge larvae) and micro crustaceans. Feeds partly on mollusks.
FurnitureOccurs in billabongs and streams in slow to fast-flowing water that is clear to turbid with rock, gravel or sand bottoms.
Studies indicate this species frequently associated with aquatic vegetation. In captivity they prefer to rest in dense bunches of plants such as Limnophila and Vallisneria. These fish can be prone to sudden bursts of speed when startled so avoid sharp rocks that could cause injury.
CompatibilityPeaceful, one of the less active Plotosidaes kept in captivity. Not an aggressive fish, but larger specimens may be territorial amongst themselves.
Suggested TankmatesHas been recorded in the wild as occurring alongside related species Neosilurus ater, N. hyrtlii and N. mollespiculum. Avoid keeping with aggressive fish. Dither fish from the families Melanotaeniidae (rainbowfishes) and Ambassidae (glassfish) are recommended. Smaller Elotridae (gudgeons) from the families Hypseleotris and Morgunda would also be suitable.
BreedingNot known to have been bred in captivity and little is known of its reproduction in the wild. Matures at 100mm TL for males and 110mm TL for females. Rising temperatures and onset of wet season trigger migration to spawning areas in muddy lowland lagoons. Females contain several hundred to a few thousand eggs, approximately 1.3mm in diameter.
