I don't think many people have successful ram spawns, at least they don't report it if they do.
I don't think I've ever seen any home bred rams for sale in the classifieds except by a few select breeders, that was one reason I started breeding them. Getting the fish to breed is easy, most healthy adults will do it on their own, but hatching and raising the fry to adulthood is a different story.
I bred EBRs and gold rams, hatched and raised fry artificially fairly easily once I figured out all the quirks. But then I had a few reports of random dieoffs of those I've shipped out, so at that point I focused on hardier fish species.
