From what I have been told, and I am doing research anems can sting corals, I handled my anem quite a bit today getting her out of the transport container and out of the aclimation bucket, but it just made my hand tingle for a short time nothing big. I hope she stays where she is now, but that is why I am putting my anems in first so they can get settled in, that way I hope when I put some corals they will be happy enough not to roam the tank.
