Yes, I know I am a newb and the flowerpot is out of my league, so purchasing one isn't an option at this point. I've been told that these things are difficult if not near impossible to keep. My question is why?? These are probably the most beautiful corals I've seen. (Although I'm quite fond of fox coral) Is there some sort of unique feature that makes keeping them so darn tough? BTW, my shrooms are HUGE. Whoever advised me on buying shrooms as my first --thank you.
