I don't think it looks like a L170 either. I think it looks more like L069 Ancistrini sp., or a L080 Peckoltia sp. Check out the link below and look them up and see the pics.
Doesn't quite look like L069 - the fins are more spiky on mine and the face pattern seems a bit different, also mine seems to have more spiky gill covers
Doesn't look quite like the L80 either - face pattern, looks more like it shape wise than the L069 though, so I'd assume it's a peckoltia sp.
