What klind of toads do fire belly toads get along with?

SAME size fire belly toads. If they arent same size they could get cage territorial and kill eachother, so make sure they are the same size OR around the same size, but have a big cage..mine, Violot, lives in a fish tank its BIG and she loves it and im getting her a friend frog today..he might be more than a friend though..idk. Hope I helped!!
