Anemone help

It's been a while since I posted. My 55 is now stocked with a pair of clowns and a juvi yellow tang. Today I just added my first coral! Yay! A little colony of zoas, and I also just added an anemone. Ever since I added him to the tank (25 min ago) he seems super flat and droopy? Is he just stressed? Should I feed him? He was last fed yesterday I believe. Any ideas? Picture down below

water conditions:
pH: 8.1
Ammonia: 0
Nitrite: 0
Nitrate: 5
Salinity: 1.025
