Size 900mm or 35.4" SL. Find near, nearer or same sized spp.
IdentificationOccasionally amongst imports of Oxydoras niger there are some slightly different specimens which tend to have black coloured fins and a grey coloured body. These so-called contaminants are Oxydoras sifontesi.
SexingThere are no known external sexual differences. There are however some thoughts and suggestions that there may be some differences in the shape of the bony plates which extend from the head to the edge of the pectoral fins. It has been suggested that the male has a more pointed plate, whilst the female has a more rounded plate. There is no scientific evidence available to support or refute this observation.

FeedingReadily accepts all manner of prepared foods. Sinking Catfish Pellets are high on the list, alongside floating pellets and sticks, as well as frozen bloodworm, chopped mussel and earthworms.
FurnitureLarge pieces of bogwood and clean plastic drainpipe of suitable diameter for them to hide under. Ideally heater guards should be provided in order for the fish not to burn themselves.
CompatibilityA real "tankbuster" if ever there was one. Quite a character; obviously suited to large accommodation especially if keeping a number of fish together. Peaceful towards other fish and members of its own kind.
Suggested TankmatesOther doradids such as Spotted, Striped (or Humbug) talking catfish. This fish is truly peaceful and can be trusted with fish of smaller size although anything without armoured or other defence and smaller than around 20% the size of the catfish is risky.
