I have a story for ya. A whiile back I got a Orange cap moni frag from Eve. I proudly glued it on a rock and it looked sooo good. About 2 months into having it it turned completley white and I thought for sure it was a gonner. I decided to aquascape my tank and in the process I knocked the frag off the rock it was on. I decided to bury it in the sand and forget about it. A month later my giant pistol shrimp dug it up and I guess the water flow carried it over to the front of my tank. I left it there for about a week (kept forgetting to take it out). I took a llok at it and noticed polyps were out and it was turning pinkish red. I left it there and the color seems to be coming back. I have not moved it from its spot. I want to see if it makes a full recovery before I move it. I then realized corals can bounce back. This thing seemed to come back from the dead.
