Hey ff, about five days ago I received two leopard frog tadpoles in the mail. One was fatter than the other so I'm going to call them like that. So the first day the fat one was swimming around the container while the skinny one was kinda sitting there not moving. Five days later the skinny one is not so skinny and it's the fat one I'm worried about. It's floating at the top of the tank and not moving and eating like the way it Was before. It also does have the clear bright colors of the skinny tadpole. I don't understand, yesterday both tadpoles were happy and healthy
