I would avoid most Ranids in a tank of this size, especially green frogs Lithobates clamitans melanota. These frogs have powerful legs that can launch them quickly away from danger. They can be skittish as well. You combine those two elements in a small tank like a 20 and you will have a bruised and battered frog. BTW. Lithobates pipiens is the northern leopard frog.
