Yes, I'd call it a Silurus sp. and would make it my first priority to figure out the species ID, read the revision, FishBase, etc. and find out how to tell soldatovi from meridionalis and from all other genus members.
As you can see, it is not an easy task, and like all vendors Rod goes by what his suppliers call their fish, if it is something poorly known or uncommon. You and I still don't know it and we don't deal with hundreds of fish weekly, so I don't see how I'd expect Rod to know. But at least he knows what he bought it as from his suppliers.
Is this the fish you bought? $35 on sale, was $45

Rod is calling it a Chinese wels aka meridionalis and he attached this photo... which upon search on Google I found out is a photo of wels aka glanis... so this is not helpful, I agree, even misleading.... but with such a specialty fish, I believe buyer must research, knowing full well that vendor has no time for it...
