I'm an acro guy. I've been in the hobby for 20 years but really havent kept zoas in almost 15 years due to keeping angels which will eat them. Recently I set up a small 8" cube on my desk and decided to try out zoas since I can't keep them in the main tank. Maybe this is the acro elitist in me but I really expected this to be a easy, low maintenance tank lol. They're doing... okay... but really could be doing better. Some are open, some are closed, some are kinda open but not all the way... only one frag has actually died though.
So my question is, in general, what do zoas like, and what in particular don't they like. High or low nutrients? Any particular parameters which they appreciate elevated, minimized, or stable? Better to err on side of higher light, or lower? Should they be fed? It's kind of blowing my mind that I've got acros growing out of the water but I'm struggling to keep a few zoa frags alive lol.
