One frag of Cespitularia/Blue Xenia available. Regular DBTC rules, and please pick up from Feb. frag swap. If more than one request, please pick numbers from 100 to 1000 (in increments of 100). This coral requires high lights (to get the blue coloration) and indirect flow. Mine sits at the very top of the tank (just under the water surface) under 70 watt 10,000K MH bulb. Please make sure you have stable tank conditions. It is considered a more advanced coral.
