I've feed some river snail My mom pick some river snail from a garden somedays. She put them in a bow, fill water in it, and feed grass that get from river. I think the river snails may like eat rice, so I put a little rice into the bow. Unfortunately they don't like this, and run away quickly. This morning, I found something interesting. They are spawning！the eggs are bind inside a sticky tape which attachment on the side of the bow. they looks like pearl but in transparency color. It is the first time i've been seen things like that.
