This fish is almost never a direct import can be be found by the aquarist with a discerning eye as bycatch among shipments of the more common Platydoras armatulus (often labelled P. costatus).

In P. armatulus, the white flank stripe continues down the body and onto the caudal fin. The caudal fin of A. cataphractus lacks the white stripe and is mottled.
|Sexing||Females typically larger with a more full, or 'plump', appearance.|
