I already have one oto, but he's not doing a good job on getting rid of the diatoms in my tank and I think it's because he's all alone and can't do it all himself so should I get a few more otos or trade in the oto I have and get either amano shrimp or nerite snails? I also have green algae like in the pics below so I need something that will eat that as well.
