How much room would I need, at the minimum? And is it acceptable to allow the bigger tadpoles/froglets to eat the smaller ones? Because the way I see it, I think the result will be a much larger ratio of strong frogs to smaller, maybe even weaker frogs, as well as a smaller brood size. Also, I've heard that baby horned/ Budgett frogs are very cannibalistic in nature. But I'm not sure if I should do that or not.
