Here are a few update photos..... all taken under two ATI Coral+ and two Reef Brite one XHO and one normal output both are all blue.
grown from a frag, this is probably one of my bluest coral unfortunately it doesn't completely show in the photo.
this one was id'ed as exquisita acropora from a reliable source
here is the same coral last year as you can see the tips are stating to turn yellow/green. it's just not a pretty blue coral!
here is my icefire echinata with full polyp extention
here is the same icefire echinata without polyps
