I have a pulsing Xenia frag plug to give away, originally from Gerber's. The Xenia hopped on to one of the live rocks and is doing very well so I don't need the original plug any more. My only caution is that I am trying to eradicate some Caulerpa in my tank right now so you should give the plug a good check over before putting it in your tank. I live on the west side of Kettering.
