Mine was a gift from a rather sketchy reefer... any ways. I didnt know it was called White Pom Pom untill now, but unlike the rest of the xenia family it seems to grow pretty slowly. I have no trouble keeping it under control and have actually been trying to grow MORE of it. Its beautiful, and EXCELLENT for my small 20gal system. I just really want to try some stony corals... so far ive done well with the xenia, shrooms, zoos and I also have a VERY small frag of green star that im trying to grow. I really want to try a stony or two tho. My first attempt was green hammer, but my camel back ate it!
Any ways, White Pom Pom Xenia rocks (now that I know what it is) IMO.
