I have a Sebae also and for the first two months i had it, it was all the way in the back of my rock work with very little light. One day i woke up and went to check on the tank and it was out in ther front. When i purchased it it was somewhat bleached but it had no other signs of desease or injury. When it came out it was completely bleached but about a month later, it was purple and brown. The only time you should move the anemone is when its either killing your corals by moving about the tank or if it is falling apart
