Hey guys, what are your thoughts on adding an otto to my betta's 3g eclipse? The only reason being, algae collects considerably fast on the acrylic walls. It seems the more I scrub it with an algea brush, the faster it grows back. My experience with ottos in my other tanks prove to be quality maitenence men. I have one in my 20g and I havent seen algae since I put him in. Thanks.
