Well, not to hijack your thread too much, but just took some update photos of my ritteri.
My pH was a little lower than what I thought (8.1) and my alkalinity was down almost at 8, so I used some buffers this afternoon to raise both up (will test again tomorrow). The anemone still has a bit of mouth showing, but he looks healthy and happy, has sticky tentacles and a good base, and shows no other worrying signs other than a mouth thats been open longer than I thought it would be during the acclimation process.
Also, I found out today from someone at the LFS that the anemone was in another hobbyist's tank for over a year before they traded it into the LFS a couple months ago, so this guy should be pretty hardy for a magnifica, hopefully I won't screw it up.
