While I appreciate the analysis, I am skeptical about my guy being anything else but the farmed nemurus. It looks pretty typical and it is an albino, both of which argue that this is merely a farmed nemurus runt.
We know almost nothing apart from what's in Dr. Ng's revision about the new 29 Hemibagrus species but one thing is clear that none of them are farmed and albino almost never occur in the wild.
Finally, I have to find and reread my ID thread but IIRC, I think the consensus on PCF was that my guy is a nemurus.
If you have carefully read Dr. Heok Hee Ng's revision though, you know 100x more than me because I have not been able to take on it yet in part due to time and due to its enormous size.
