That's interesting. I have a small mushroom leather basically in front of the one mp40 and it is happy as a clam.
Speaking of clam, hasn't started fully opening back up yet, but the mantle is fully extended on the derasa. Looks like it was the coral beauty all along. I'm suspecting a similar issue with one of my pocilopora...which is right above the clam. On my days off, I'm going to figure out how to move things around so I can make a larger 'cage' for the clam incase it is stopping it from fully opening...though it doesn't appear to be at this time.
While doing all of this, I have continued watching over my orange Montipora Setosa. Really cool monti if you've never seen one. Pretty slow growing...but it decided to grow into the shade of one of my overhangs and the one branch was bleaching. I gently moved things, which broke afew chunks off of the marshall island latana on the other side of the rocks, and it should be fine...but I did decide to frag a small chunk off and secured it to the rock holding down the clam's cage for the time being.
