I agree with Blue Cray, I'd add 3 more cories to the mix. Don't be afraid to add more ghost shrimp too, they don't add much bioload. Otos tend to stay stuck to glass, plants, etc so they won't be on the bottom too much. It'll be a very well-stocked tank, but as long as you do good weekly water changes and have a very powerful filter, you should be fine.
