Rose anemone shrinking - help needed

[jsousa]

I've had my Rose for about 3 or 4 weeks now and it seems that it is actually getting smaller. When I first got it was about 3" inches across, then after about a week it grew to about 4", and now over the last 2 weeks it seems a little shriveled, definitely less than when I bought it.

My parameters seem acceptable - My tank is predominately SPS and they are thriving. I have many LPS also which are doing exceptionally well. Lots of good growth and great expansion.

pH 8.1 - 8.2
SG 1.026
Temp 79 (maintained by chiller)
KH 12.8 (seems a bit high - maintained by MTC ProCal Calcium reactor)
Calcium 440-450
Mg 1330
Nitrate <5

I target feed all my corals and the anemone with Mysis/Rod's/Coral Vibrance mixture once a week just before I do a 10% water change.

Any thoughts as to why this might happen?

has it started to turn white yet? resson i ask is that i had one from the lfs that done the same thing it shrank to the size of a dime turned bleach white and stayed like that for over a year. it also moved slowly around the tank in that time .finally it worked its way to the top of the tank in good light and good water flo and started to expand within two weeks it had regained its size and looks great . hope this helps

Agree with deadclam. I had a bta look like that for a few weeks before it found a better spot with more flow and came back to life. (but of course, it did this only to commit suicude a week later in a powerhead).

False alarm. Today he's even larger than he was before. It could have been that I only feed him once a week. It could be that that is natural for them. I'm really not sure. Anyway, thanks for your help. I'll let you know if anything happens.
