Hello. I was cleaning the sides of the tank with a sponge when I saw that my Kenya Tree, which was getting huge, was literally cut from the stem and the rest of the coral is nowhere to be seen. It almost looks as if it was eaten by something. I can’t believe it. This was my favorite coral in the tank out of the bird’s nest, leptastrea, and mushrooms, all of which are doing wonderful. What could possibly have done this?? I have a clownfish, goby/pistol shrimp pair, and two trochus snails. I have noticed that there have been tiny starfish in the tank. I believe they are asterinas, but I can’t tell. Please help.. The photo of my coral shows it several months ago and it was much bigger than that.
