Yeh know what you mean about H nemurus being thinner, but to be honest think there is still a lot of confusion between H nemurus and H wyckioides, as H wyckioides was once sold under the name of H nemurus. H wyckioides is a long slender catfish compared to H nemurus, and if it was in albino form you would never see the easily recognizable red tail,and white maxillary barbels. on some sites the max size given for H nemurus is a little on the large size, not saying ive seen loads but ones ive seen barely if ever reach 18" never mind the quoted size of 2ft+.And H nemurus is also farmed in the far east in the albino form. anyway il post a pic and see what you think, compared to yours think body shape is pretty spot on.
