Yeah... I've been really really happy with that purple cup (Turbinaria mesenterina). I got lucky when I placed it where it is. I've taken a hack saw to it twice now, the last time to "open up" the front so the polyps were more visible and it didn't trap as much debris in the bottom. The "frag" from that cutting session can be seen on the center back wall, waiting to make a trip to the LFS
now that it's all healed up.
Now if that Stylophora just above it would stop trying to grow over it and shade it, I'd be even happier!
