Since the photos of the farmed Hemibagrus were left in the nemurus datasheet, I think that yours and mine and everyone else's are the nemurus. I used to think H. spilopterus but I am backpedaling now that Silurus and the PCF team had the time to sort out the Hemibagrus photos, I presume...
So if I mislead anyone, I apologize. I am still not certain though but for now I think I will call them nemurus.
They are said to max out at 2'+ but we get the refuse from the farms that appears to not exceed ~1'.
