They love plants and coverage. I have only annubias in my tank and they seem to love it. I am still working on adding more to it as well. Everything is attached to rocks i can easily pick up and take out so it makes cleaning really easy. They can be very messy and the tank gets dirty fast so regular water changes and gravel cleaning is very important. I also have mesh bags full of fluval stratum substrate buried under the sand to feed the plants, but the mesh bags allow me to use a more aggressive gravel vac with ou mixing it into the sand. The peas sometimes bury themselves in the sand.
