Sorry just an additional though to this. I think the main thing that could be a factor to help with breeding is one extremely heavy rainfall session as apposed to small rain falls sessions. I am busy with my White's Tree Frogs at the moment and when I put them in the rain chamber I will leave the rain running for 4 hours a night for 2 weeks, but this is the complete opposite for Pixies. We will have rain which will be mild downpours that will wet the soil and bring insects, rodents, reptiles and amphibians out and hunting, but there still will be very few water pans and they will be small and shallow. I think the right way to do it it to almost fill a rain chamber from a shallow to 50mm over a 4 hour cycle and then have smaller showers there after cycling the water already in the rain chamber. Does that make sense?
