I've found them to do just as well as most wild zoas, as long as you treat them right when they first come in. I keep mine in lower light, moderate temps, and good strong flow for the first month or so, and then they can be adapted to regular conditions without too many issues, IME. I have the fruitloops, the ones called emeralds on fire/firefrogs, belladonnas, and a couple others that I got and haven't had any issues with so far.
