Well hopefully I got rid of the last of my silver branch xenia. Removed and traded 2 large rocks today and will take the last tomorrow as well as the little pieces that i fragged from other rocks. Very cool stuff but just grows too fast. I am sure there are small pieces left somewhere that will spring up but I will deal with them when the time comes! Hey in my tank the stuff was pulsing like mad and the stalks while fairly long were more bushy in appearance. The tanks I have seen my frags in dont pulse at all and stretch way way out and look completly different. What causes them to stop pulsing?
