I'm not a fan of crabs tonight. This morning I caught me emerald crab chowing on a Stylophora. It was before the lights came on so I thought "maybe he's just eating some micro algae or something". Came home tonight to find 50% of the stylo polyps gone. I start taking a closer look and there's more damage to other corals. So I catch the Emerald and banish him to the QT. Come back upstairs and notice that the one fairly large blue hermit (he's all blue and significantly larger that a regular blue leg) has been parked at the base of a digitata for at least an hour so I grab him and sure enough he's made a feast out of the base. I don't know if this just started or what but it just ended tonight...
