Neocaridina heteropoda var. "red" (Cherry Shrimp): more specifically, breeding them

Generally speaking, if you have them (assuming you have a mix), you'll probably breed them.  They're not especially difficult, but like many of us (not all, but many), they prefer to do 'their business' with a little privacy.

Adding generous planting will help and moss is a favourite.  Java moss (Taxiphyllum barbieri) is easy to grow, I prefer Christmas (Vesicularia dubyan), it is a little harder to grow but I think it looks nicer and gives a denser pack. Live plants will help keep the water quality right, but try and stay on top of your water changes, shrimp aren't too keen on nitrate, so choose some nice ones and have some fun with it.

The aquarium, filter etc.

I'm using an old Fluval Roma 120, 90cm, 120 litres which I filter with a Fluval G6. You'll either want a prefilter (sponge) on the inlet or better yet, just use a sponge filter; they're really cheap and will ensure your little babies don't end up in any trouble.

If you have a fairly dense plant covering, you'll likely be fine, but otherwise, think very carefully about what fish you have in the same tank. It's very different to have a tank which you're using to breed shrimp and a stocked tank which you're hoping shrimp will breed in.
