You can get some breeding grass at Walmart in the fish dept. Its just a small square of plastic "grass" and it works great for baby shrimp. Once you notice the Mother shrimp has eggs, segregate her from the main tank. One of those tiny 1 gallon critter tanks at Walmart will work great. Put her in the tank with the breeding grass in the bottom of the tank and wait for her to lay the eggs. Once she does, remove her from the small tank. She will probably die soon afterward. The babies are SMALL!!!!!!! The rest of your fish in the main tank will eat them most likely, so try to keep them seperated untill they are grown. Not sure what to feed them....newly hatched brine shrimp would be my best guess.
