I am "building" (yeah, right, a one gallon) RCS tank. I have it set up and have 4 RCS (2 male, 2 female) in there. I am hoping that they breed. I have some sort of moss (not sure, wasn't labeled at LFS) in there for them. They like it. I fed them some shrimp (cannibal! I know. Lol) pellets and they seemed to like those but I want to get them better food. What are some good foods for them?
