I know algae eaters do. We have a 32 gallon BioCube and those 2 things are massive. Wish I could get someone to get them and place them somewhere without killing them. Our aquarium days are over.......;)
Wrong type of algae eater - plecostamus. Quality fish storess only sell these for ponds. They grow to 4 feet long. There are many much smaller algae eaters that are perfect for aquariums. Look for a bushy nose or rubber lip pleco.
