So, I went and dumped some crickets in the vivarium, and then just as I looked down I saw that one of my males was clasped onto the back of my biggest female. He was hanging on for dear life as she was hunting down some crickets. I went to grab my camera and when I got back, they were separated.
I really don't want baby frogs, so I have kept the water levels to a minimum in the hopes that the breeding environment wouldn't be suitable. I guess I'll be on the lookout for eggs now.
