I bought a Red Emerald crab the other day, and am now starting to wonder if it is a decorator crab after all. I saw it getting a little violent towards my hermit. Also, it's a little pointier between the eyes than others I've seen. I noticed too it has mowed down a few of my fan worms, and now has 3-4 of them on it's legs. I've never seen that happen with other Emeralds, so I am wondering...hmm...
