Going for L066 then. Thanks all.

Thanks for your help guys. So would it be fair to say I have five L066? Anyone think differently?

Last couple of pics.

Hi everyone, I wonder if you could help me with identifying these plecs I recently bought. They are all supposed to be the same species. I see two are a different colour form, if indeed they are the same species at all! I think I can work out the sexes but if anyone wants a stab then great. Thanks.
