I have two plecos that I purchased as 'albino plecos' the female is a longfinned albino pleco and the male is normal finned. I know that they can have blue, black, or red eyes. I know they for sure aren't red but no matter how much research I do I can't seem to tell the difference between blue and black eyes? I guess my question is how would I tell the difference? Also the female is more yellow than white like the male, so does that make her a lemon pleco not albino? They recently layed eggs and I'm doing a project for an agriscience fair based on their genetics so I need to know for sure. Thanks!
