I've read mixed things. Some say they only uproot plants, other say they devour them. I would like an algae eater that is big enough it doesn't get eaten be my 9 inch bullhead catfish. The only other one I could come up with was Chinese algae eater, but they only sell super small ones around here. The plants in the 45g tank the pleco would be in are various swords, vals and floating hornwort and elodea. Thanks!
