Thanks Terry, I'll have to find that book. I like things that thrive in spartan enclosures, that means it's harder for me to mess it up. If they are pretty hardy, I'm going to have to give them a try. I see the Painted Mantella (Mantella baroni) for sale at $20 all the time. Darts get so expensive, I can't spend $60-$120 a frog, plus whatever shipping is because here in southwest Missouri, nobody sells darts or mantellas.
