EtymologyOrinocodoras: From the Orinoco River and doras, meaning skin (also a word commonly used in forming generic names for doradids); in reference to the distribution. Species named in honour of Dr. Carl H. Eigenmann, Professor of Ichthyology in Indiana (1863-1927).

Size 200mm or 7.9" SL. Find near, nearer or same sized spp.
IdentificationCan be distinguished from Platydoras armatulus, the striped or humbug talking catfish, as follows: snout is more pointed, whereas P. armatulus has a rounded snout. Eyes of O. eigenmanni are smaller. O. eigenmanni has a longer adipose fin. The skin of O. eigenmanni looks less plated and in almost like sandpaper in areas. Generally, the 'Orinoco' is by far the most elegant fish of the two.

Soemtimes imported under incorrect names. Anyone who is interested in O. eigenmanni must look carefully through shipments of P. armatulus, for that is where they may be. And if so, you will easily spot them.
SexingMales are smaller and slighter. In larger fish a top view may give something away: males are more slender, adult females are more than 25% larger than similarly mature males. Differences in belly colouration have little to do with gender.
General RemarksA monotypic genus.

FeedingWill eat anything; particularly fond of bloodworms and pellets or tablets. Is very visible when fed, even during the day.
FurnitureDriftwood for hiding places. However, as the fish grows quite large, see to it that it remains able to swim. If necessary redecorate. Will not ruin plants. Ensure heater is not used as a hiding place.
CompatibilityA community fish for medium to larger aquariums; not suited for life with very aggressive fish or very, very small fish, the later may accidentally be regarded as food.
Suggested TankmatesGoes very well with other peaceful catfish and characins. Can be kept alone, as a pair but best in a small group.
