I'm not really breeding them. They just seem to have babies. They must like my tanks water conditions. I have had Red Cherry babies, Yellow shrimp babies and I discovered a tiny baby from my Tiger shrimps the other day and I only started with 4 Tiger shrimps. They are safer if kept my themselves. I like keeping them with my Tiger/hybrid endlers and my 1 bushy nosed pleco. I have floating Hornwart plants for them and alot of plant cover in my tanks. The females are a brighter color then the males and are bigger in size. The females have a saddle with undeveloped eggs that they will carry underneath when they start to develop. If you want to get them I think that Aquabid is a good place unless you find someone in the forum that is selling them. You can also try craigslist as I typed in shrimps in the pet section and in the general section in my area and was able to find some people selling some red cherrys for really cheap, and Cyrstal red shrimp for $3 each as in the fish stores they sell for $6 each here in San Diego. Fish stores sometimes do not carry the certain species type. I have noticed that the Plantinvert site has high prices. This site is a really good site for the information and they have some amazing pictures of the shrimps. Red Cherrys, green, yellow, are easy to breed if you start with 8-10 of them. If you can tell females from males then 2 female/2 males would be a good start.
