And I just came back from vacation after being gone for 4 days and my xenia totally moved off its original rock to a one up higher closer to more water flow...it actually moved more than what I thought it could in that time frame...I never had any of more corals move that quickly before.....Also, should my scoly be sitting down lower? Possibly on the sand bed? It doesnt have a lot of color, and it really never has had a ton of color. I dont know if it would help the color of it by moving it further away from the light.
