I have a good deal of algae in my tank and just added an Oto. He's happily sucking away. Is the tank's algae enough for him? I bought spirulina discs and added one on Day One -- my three platies ate it and promptly became very bloated (I was really worried -- thought they were all coming down with something). Second question: is it safe for them?
