Description: The base color of Oil Catfish is whiteish or yellowish, with irregular reticulated black pattern. The fins are clear. A nocturnal catfish, which feeds in the open water, near the surface. Females are much rounder than males when gravid. The male's anal fin is modified with the first and second ray thickened and longer, similar to the gonopodium found in livebearing toothcarps.

They only spawn, when the tank has a moderate to fast water flow, and has lots of small crevices where the eggs are laid. Fertilisation takes place internally, via the modified anal fin of the male, and the eggs deposited 24-48 hours later in the small caves by the female. The female guards the eggs until they hatch. After 6-7 days the fry use up their yolk sacs, and can be fed with microworm or brine shrimp nauplii. Like the adults they will only feed during the night. They prefer to hide near the surface. Fine-leaved floating plants such as Riccia are ideal for this purpose.
