Looking for some input please. Have a 38 gallon low tech planted tank. Already pretty well stocked with 2 angels, trio of apitos and 15 cardinals. Dont want to do a bn pleco, has them eat plants in the past and too much poop. Thinking either 5 or so ottos or 5 or so amano shrimp. Amano shrimp probably would be angel food? Although they haven't gone for the cardinals. So maybe that counts for something?either way which would give me the best algae eating potential? Would 5 of each be too much? Looking mostly for sonething to help with algae on the plants and thr glass and rocks would be a bonus. Cheers.
