Those look great, guys! I honestly don't know why more people don't keep them. Ime they are the easiest anemone to keep as long as you feed them. Tzwizzle, I have had mine for a few years in a tank with only 1/2# of sand. I used mostly branch rock, and they seem very happy with their tubes in the nooks of the rock, with the crowns sticking out. If they are not happy where they are, they will abandon the tube, find a more suitable spot and build a new one. You can always provide pvc pipe for the tube if you want one without a dsb, although I really don't think it is necessary, unless you have crabs that may pick at the tube.
