Ritteri

[Nemo]

I have a Ritteri anemone, and it is doing well for the most part. I have had it for about 1 month now, and every day it goes through a phase where it shrinks and looks like crap in general.
All other anemone's in the tank are doing great and look great all the time.

Ammonia = 0
nitrates = 0
ph = 8.2
salinity = 1.023

I feed it every other day with a little bit of scalop, it does not close up and take it right away like the others, never has. ( I also have 2 percs hosting in the Ritteri)
As per what I have read I should feed it about three times a week, give it high water flow (I have a power head deflecting off the glass towards it and i have a return line running about 1" above it, it has a nice wave action)

Any thoughts as to how to make it so it is open and looking good all the time? Any comments would be nice.
