Pleco

Do Pleco stop cleaning algae off glass when they grow up? Mine did an awesome job as a baby and has gotten lazy as an adult - 7" BN male

Mine doesn't bother with cleaning now either, she's 5 inches. My bulldog still cleans the algae off the glass and he's older. So yep they get lazy lol

I have heard that they can loose interest in it when they get older. Not sure if it's true for all kinds or not.
