Down Species Information
Size 200mm or 7.9" SL. Find near, nearer or same sized spp.
Identification Can 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.
Sexing Males 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 Remarks A monotypic genus.
