I just bought an "already set-up" tank about a month ago, and that is what I had was a condy, it was very easy to take care of. The only problem I had was that it's foot kept twisting up, which from asking quite a few people seems to be a freak occurance. Some had heard of it, but most hadn't, and I was told just to literally untwist it. Anyways, like I said, I think this was a freak occurance, and otherwise it was very easy to take care of. Mine was already attached to a rock when I got it, and moved around on the rock just a little, but not allover the tank.
