Don't bother with cons, you'll never be able to sell them. Also, rams are tricky to raise the fry. I've had several spawns, but none of the fry survived. I would suggest kirbs, at my lfs the "krib" tank is usually empty meaning there is probably a high demand for them in my area. I'm not sure about yours, but you could always ask your lfs manager and see what fish he would buy off you.
