Okay, so I recently got tadpoles for the first time. I ordered one and was given three, I've been calling them Larry, Moe, and Curly.

They're in a ten gallon tank with river rocks on the bottom. I have a filter in there. They kept getting drawn into it so, I semi-blocked the intact with big rocks.

They're doing this things where they occasionally swim erratically from one end of the tank to other. They keep banging their little heads. I'm worried they're going to hurt themselves.
