You could set up a tank for the snails and tadpole, that would be nice! Put lots of plants in if you want it to look like an aquatic garden.

Up to you, they do no harm if you leave them in but some people don't like the way they look, and if you overfeed (most people do...) then you'll soon end up with 100s of them.
