Still wondering how one could tell them apart. The only one i can easily identify is suchus. The rest - only fro the pic, as a livin fish they all look the same to me.
My friend, I wrote the sticky, and even I have a hard time with these things unless I can actually investigate the fish in person. That sticky took two years of research, had two investigators (myself and E Estarego8 ) and heavy consultation fromDr. Hoek Hee Ng. It was enough to get Julian Dignall of Planet Catfish to change the Cat-E-Log to reflect the changes, and Dr. Ng is now currently researchign the genus in an attempt to more properly refine it, to include naming sp. 'indochina' and sp. 'dwarf'.
The long and short of it is that these fish are particulalryl difficult to identify even under the best of circumstances, and many of us, to include myself, have guessed wrong from time to time. There are no concrete diagnostic traits written to date, even though these fish have been known to science for well over a century. I hope that the good doctor can provide us with answers sometime soon, so that we can finally iron this out.
