What animals live in rice fields?

How do rice fields stay flooded?
Normally rice is planted in dry paddies, and allowed to sprout a few centimetres. Then the paddies are flooded over the course of a few days, to simulate natural flooding patterns. In some areas the rice is planted in already flooded paddies, when its sprout is tall enough to reach over its companion plant (Azolla).
