The tank got a new inhabitant. A large green wild-collected BTA.
Anemones are infamous for their wanderlust. This one did not like its dedicated location. After it slid from the rock, I helped it out to a similar location at the other end of the tank. It stayed there for a few days, looked happy and bold, had a very good attachment, but was still not feeling home-sweet-home, and so it went around. After visiting a few locations, this is where it is now:
Seems, I got a cave anemone.

. Jokes aside, I know this is not good. For now, the nem looks fine. It's inflated, mouth closed, body column and the foot look fine. It moves actively reaching out with the foot. (I actually had no idea that nems can extend/contract the foot so much.) I tried, unsuccessfully to persuade it into some other 'perfect locations'. I will leave it in that cave, unless it start showing signs of deterioration.
Also, I got a decora goby. The goby is in observation tank for now. It was quarantined by the LFS, looks very healthy, eats a lot. What a facial expression! Bits my daughter when told to clean up. More about decora once its in the display.
Water params are fine except bottomed phosphates. I keep dosing, and feeding to keep them a hair above 0. Nitrates are ~5ppm. Coraline growing fast. Supporting with A4R. Feeding with frozen mysis and dosing quite a lot with phyto (Nanno, Tetra and Chaetoceros). Tank is full of amhipods and copepods. Sycon sponges started growing a few weeks ago. There are a lot of them now in the sump. One even grows on an astrea snail in the display...
