What exactly are you looking for when it comes to IDing plecos? I mean I looked up the L82 on plantecatfish and he is a spitting image of one of their pictures
you know after looking at the Linus it does look just like the juvenile L-280 how big does the L-280 get before the fins start to darken? Just so if I see him getting bigger then if he gets darker I can know the difference between the 2 right now he is about 2 1/2 inches.
