They aren't hard to keep at all. I've got seven of them one by itself in an 18x18x24tall viv and the rest in a 75 gallon. I had never owned a frog before I got the first one so I think beginner is a fair description for the skill level required.

I've always fed mine every two days as well. Mine seem to be more active than other ones I've seen, this may be partially because both the petshop I got the first one from and the breeder I got the others from feeds during the day. I do as well so I think they have gotten used to a slightly sporadic schedule.

The only issue I've ever had was a prolapsed cloaca, which I was able to solve thanks to this site and another one recently that I was able to fix immediately this time.
