i have a bad problem with algae in my 90 gal cichlid tank, i need to know what algae eater i can get, i have two Synodontis cats, one is a rare sucker mouth cat but he does not eat algae, so i need one that they will not bother and one that preferably has good coloration but i need one that can hold its own, my biggest cichlid is a red empress and he is about three inches, any help would be awesome
