Carpet anemone shrinking

[ChillingBoy]

I got a blue carpet anemone over 2 weeks ago about 14inches wide and now it's shrunk to about 5 or 6inches. It was eating the past 2 weeks and havent eaten the last couple of days. Did a water change already. 75 gallon tank with 2 175mh and 2 vho actinics with 2 820 seios and return pump. Water parameters looks good. All other corals doing good too. Any ideas what is wrong?

post water params (including temp and salinity) for a start. It would also be helpful to know what other livestock you have with the anemone.
What kind of "blue carpet" anemone is it?
