exo terra: thats the ultrasonic one you are talking about right? I bought one of those about a year ago and LOVED the fog it put off, and the cool effect it gave my tanks.. but definitely a piece of ****, it quit working in about a week.. Thankfully I kept the receipt and returned it.

Hygrotherm: i was looking at those on amazon, is it worth the 70$ just for humidity control? it sounds like a really neat thing to have for my dart frogs tank but sounds like you would need a seperate one for every tank which sounds like a fairly costly investment. Also, im sure that the extended lifetime it gives the reptifogger is well worth it.. right?

On a second note, does anyone know what humidity levels Red Eyed Tree Frogs prefer?
