I've had two poison dart frogs for 7 years and a Cham for a little over a month. Right now I think the Cham is harder, but I'm not sure if that's just due to the learning curve like I had with the frogs. Once the environment is set, the real concern are the feeders. For the frogs it's basically just fruit flies and some other treats every once in awhile. My frogs have never EVER gone on a hunger strike or got bored of their food! I have read that that is a real possibility with a cham. So, I find myself having superworms, silkworms, dubia, hornworms, butterworms, houseflies, and blue bottle flies! A bit more than the frogs ever needed (or wanted). Much of my time is spent caring for the feeders. So, make sure that is something you can provide AND enjoy.
