I've just added some cured Live Rock to my tank and placed it on the sand touching my existing rock which I've had for 3.5 years. From what I've been told and read on the net, this rock should be live as well although I don't think I've ever seen the PODS on the glass. How long will it take before I see any of the PODS from my new live rock? Is there a trick to seeing them?? I have noticed that my new Mandarin Gobie seems to be picking at my old rocks quite a bit although I can't tell if he's eating anything.
