The classification of Goonch is in my opinion now even more confusing than it ever was and I believe not helped with some of the id pictures on planetcatfish being of the wrong fish. That said, the only real thing you need to know is, dwarf, highland or lowland. Ie dwarf, cool water or warm water.
The rest of the requirements are pretty much the same.
To the old classification
Figure out if yours has round eyes or oval .
Round will mean Yarelli or bagarius
Oval will be rutilus or indochina.
It’s not the dwarf.
