all too common with these fish . let me guess it was marked up as something along the lines of spotted plec or similar? unfortunately also very hard to re-home due to the size and the fact that they are so incredibly messy.
I wouldn't like to disagree with you, Mark (but I'm going to anyway!) I'd say that was a common plec; the Gibbiceps tend to have more 'giraffe' like markings and don't have the paler stripes...
Not that it makes much difference; you're still looking at 2 foot plus, whichever it is...
