Sadly

Sadly I have lost one of my corals, it has been eaten by something and I have no idea what did it. As you can see from the pic below this is what it looked like, as you can see its nice and healthy waveing its tenticles around in the water flow, even tho it gets most of its energy from the lights it still collects food partiles from the water or it did while it was alive






This is how I found the coral one morning, as you can see half of it is missing and a bit of it is lodged in the rock away from the main coral body. I tried to save what I could by moveingf it top a different location and had hopes for the next day or so as it seemed not to be touched but on the third day I awoke to find it totaly eaten, andI still dont know what did it as as far as I know there should be nothing in my tank that eats corals, Ive been very carefull with what I buy and put in there
