I've kept them cold and dry last winter. When it got hotter I made the tank more moist. I prepared a rainchamber and when a storm came I put them in it hoping I could trick them into amplexus. I didn't hear any calls though and they were all about the same size. I'm affraid they were all females. With my new youngster I hope to have a male. I'm going to try the same thing next year. I'm also trying to get more animals.
Isn't there anyone who has bred them?
