They are Hemibagrus. The genus used to have 3 spp. Now 18 or smth. Dr. Heok Hee Ng split them up. Not easy to ID now, have to read the revision. Plus, the fish in question and the reference fish must be of comparable age and size when comparing.
Going by old taxonomy of 3 spp., nemurus is almost never available in natural color, always albino. ARTC can be but usually rare and more expensive. Wyckiis are usually $5 and available. Hence, by old taxonomy, I'd stick with wyckii.
