In my tank with gravel, ghost shrimp have been the biggest contributors to keeping particles cleaned up. Snails and otos will eat biofilm and diatom algae, but the ghost shrimp are the ones picking all of the particles off the gravel and floating free. My gravel is spotless about an inch down (can see against the glass), then it gets real gunky, but that feeds the plants. They have fairly long arms and tiny pinchers and are constantly digging deep in the gravel for stuff. The water is spotless. It's a 10 gallon with two otos, 7 guppies, 3 cardinals, and 4 endlers as far as fish stocking. Monthly water changes whenever nitrate finally creeps up to 15 ppm. That being said, I don't know if ghost shrimp would survive in your tank.
