Not so long ago it was also considered as hemibagrus docmak although that was when the family were still considered mystus . some places no longer consider docmak at all favouring filamentosus. Most will consider it under nemurus now although I would agree on a few points.
Yet to find a large one, and by large i mean bigger than 12" .
Yes, as catfish go they are fairly friendly, although mine hates the tiger dat. They don't tend to try to eat anything larger than their mouths however they are still catfish and defend a territory. Slow growers, but probably due to a smaller adult size.
as for the eyes, are you really sure they are not red?
Thought mine had black eyes but when you look closer you can in some light tell they are actually red but almost like red glass on a black backing- almost impossible to tell they are red without looking real close.
One thing we all agree on, not albino or luecistic or xanthic hemibagrus wickiiodes - not Asian retail cats in any way.
