Also on another note: plecos are pooping machines. They might be good for cleaning when young, but when they get older most of the time, they will get lazy and stop eating algae anymore. As far as you keeping your pleco goes, we have given you advice and let you know what would happen. While I think common plecos should be banned from normal sale, and I think it would be beneficial for you to get a smaller sized pleco, In the end, it is your decision. Don't let anyone tell you what you have to do, its your fish tank after all.
