Identification This species has been misidentified as Platydoras costatus for decades, only in late 2008 was it recognised as P. armatulus. Orinocodoras eigenmanni can sometimes be offered for sale labeled as a Striped Raphael Cat or suchlike. This contaminant is most easily distinguished by its longer, more elongate snout and longer adipose fin. The contrasting white stripes on Platydoras armatulus are also considerably brighter, particularly on youngsters.
Sexing Adult females are wider when viewed from above.
General Remarks Talking catfishes get their common name from noises they make, mostly at night, by grinding their pectoral fin bone in its "socket". Click here to listen to this species.

Feeding All aquarium fish foods, sinking catfish tablets offer the best method of getting food to the fish. Bloodworm and high protein dry food are also favourites. Try delivering food at night.
Furniture Caves or pipes are a requirement if this fish is to avoid long-term stress or the possibility of mistaking a heater for safe refuge.
Compatibility An ideal community fish, peaceful but rugged.
Suggested Tankmates Anything from tetras to cichlids, preferably South American, but will mix with all community fish.
Breeding Fry have been found in the aquarium, however spawning behaviour was not observed and is therefore unknown.
Breeding Reports There is no breeding report.
