I just got this green birds nest coral. It's the only hard coral(sps or lps) in my 75g tank right now. I have a reef breeder photon light that doesn't go above 50%. I just did a 20% water change and all the parameters are good. When I first got it the polyps stuck out further even at the lfs. So I just moved it to a less brighter and flow area to see if that will help. What do you guys think?
