here is a photo of the vivarium I keep them in.
I have one CP in the vivarium a U. livida I love the little flowers and they bloom not stop.
they are not that picky on the temperature about 70 to 80 in the day and mid 60s at night. They do like very high humidity but they don't heavy air circulation so it is not a problem.
D muscipula is right, these frog are not poisonous at all in captivity. I could put them in my mouth and I would be fine. But in the wild if I were to do that I would be in a few minuets they are some of the most poisonous animals an the planet!
