Catching Red Cherry Shrimp

[melave]

Hello, I was wondering if anyone has a good method of catching Red Cherry Shrimp to get them out of your tank? I got 1 male and 2 female shrimp a while back and they got it on. Now I have around 15 of them and I'm worried if these guys breed again they'll swarm my tank! I have a small 57 litre tank and I don't want any more shrimp! I got a live plant from a shop which must've had snails on it and now I've got a load of them too. They'll be easy to catch because they are so slow but the shrimp are fast.

Any advice?

Thanks
