Ok so I got this awsome frag of sun coral about a week ago and I get it home acclimate it and place it in an ideal place. I wake up the next morning to find my new coral missing. After doing some searching I find it deep into a cave in my rock work. Luckily I was able to reach it without taking my rock apart. So replaced. Next morning same exact thing, its deep into the cave. So I take the coral out and feed it for the first time and see it open up for the first time, I must say this is an amazing looking coral!! So after feeding it goes back into a diff space. It lasts there for about 3 nights then back to the same exact spot. Again I reset it into a diff spot. It lasts until this morning. Now its in a diff spot than the cave and I def cant reach it unless I pull some rock apart. This time is a little diff. When it was in the cave it looked to be dragged or shoved in there, it would be upside down or sideways. This time it looks like someone is messing with me. It's placed perfectly and neatly onto my base rock that has an overhang, but its in the back of my tank!! So before I rip apart the tank I wanna find the culprit. I have about 8 hermits in the tank, a sifting star, a pistol shrimp, 4 chromis, a clown, pom pom crab, zebra crab, and a bunch of nessaria snails. I have other corals that aren't secured either and they are all fine and exactly where I left them. So who is messin with my head?
