Last week I moved all the contents of my 15 gallon nano into a reacquired 20H tank. It became a nice looking tank with lots of light. I decided to keep what few SPS corals I have into that tank (M digitata and Staghorn). Along with a large number of zoanthids. All was going well, but the tank looked like it needed something moving. So I trudged off to my "friendly" LFS for a fish. He had a few Yellow Clown Gobies in stock, and to make a long story longer, I decided to purchase one. I had a vague recollection of reading that YCG liked to snack on SPS corals. So I asked my "friendly" salesman if he had ever heard of that. He looked at me aghast, and assured me he never had heard of such a thing.
Well I took it home and introduced it into the tank. It immediately moved onto my digitata, and I noticed it took little nips from the coral. Yesterday I came home and noticed one side of the largest piece of digitata was all bare, and the staghorn was all retracted. So now all the bits of SPS are back in the 50 where I don't want them, and I am contemplating taking the 20 all apart to catch the miscreant. I could then catch the little puke and find a spot for it. Hmmm maybe he could go in the 10 gallon nano I am working on setting up
