+1 to jetajockey. I've got RCS (20+) in my 48 gallon with Neons, Red Eye Tetra, Danios and a Bolivian Ram. They breed prolifically, but are usually in hiding. If I stir up any of the Java Moss or plants they scatter all over the tank. They really do tend to stick in the Java Moss, but if you look closely enough you'll see them in all the plants and under my DW. They're fun little guys, but you might want to also pick up a few Amano shrimp to help keep things clean and actually be able to see them once in a while, lol.
