Thanks John, no particular queries. It would be nice to know about other peoples set-ups etc. I'm changing my frog tank this weekend, going to put a divider in to have a permanent (sp?) small water area. I've tried tipping the tank to have a wet end and a dry end, but it hasn't really worked, it's all wet! Also I wondered about substrate for these frogs. I've got topsoil and compost mixed, the frogs seem OK with it, but I wondered if it was a bit too dense?
