Yeah, they really are a remarkable species! Unfortunately, they are rather uncommon here in Sweden. No-one breeds them regularly, and when it do happens, most of the tadpoles turns out as males. For some unknown reason, the male/female-ration is incredibly skewed towards males. According to a (rather small) Swedish forum, there is a guy in Sweden that currently (accidentally :P) got tadpoles, but I do not know if he are selling the froglets or not.

And no, because of the reasons above, I have no female yet. My only shot is probably the next Hamm-expo, but it's not even guaranteed to find them there. At the latest Hamm-Expo(where I got the red eyes), there were only males for sale, not a single female. So, if you ever find a CB female, please, let me know!
