illustrae said:Amano shrimp are pretty robust, so as long as you're not trying to keep them with agressive cichlids, I think they'll do fine. They also add almost nothing to the bio load of a tank, so 6 shrimp is a good number to start with, and if you have lots of plants, and especially some clumps of moss, you may get them to breed.

If you are looking for something that will breed in freshwater you can try cherry red shrimp. They are getting cheaper and they breed more than guppies.
