They're all wild caught? I didn't know that... I thought that since they seem to breed easily, it'd be more likely they'd be captive-bred.
They're wild caught because they're easy to find and very cheap. Captive bred ones only come from a few hobbyists, and most frog people who aren't new to the hobby are not interested in fire-bellied toads because they're everywhere. So not many are captive bred.
