Check this, it outlines my experiences so far:

I have some questinons for the pro's:
1. What are some signs that a female may be carrying eggs?
2. Do the females have eggs all the time, or is it some kind of cycle?
3. Has anyone ever had the problem of the fish being out of sync? It seems when she is ready, he is disintersted (and vice/versa).
4. What does a ram consider a good spot to spawn> (Don't say a flower pot - i don't want to put one in my aquarium, and i'm sure they aren't bent on spawning in a pot.)
I've been doing daily or every other day mini-water changes, feeding a varied diet of fine foods (live bloodworms, blackworms; frozen bloodworms, frozen brine shrimp).
I even rearranged the aquarium to provide two choice spawning spots - one kinda sheltered by plants and one in a free swim zone. You can see a pic at the end of the page I linked.
