Hammer coral behavior

[CEReefer]

Hi guys, I have got this hammer coral 2 months ago, and at the beginning had all the polyps as a “normal” hammer should (mouth not exposed, ecc ecc..) but after 2 weeks started to be like this.. I waited to post as I wanted to see if it was going to improve.. why is it like this? Super open, mouth exposed.. flow? Light? What?

the shrimp has been added to the aquarium 1 week ago, so the hammer was like this for a while before the shrimp “happened”, also I feed all corals twice a week with reefroids and oyster feast

Anyone knows? It looks like this all day, could it be too little flow/light?

To be fair I really dont see anything wrong here. It's much better to have a hammer in low flow because hammers hate medium to high flow which slowly tears them apart and kills them. Too little lighting is a much better situation that too high lighting. I wouldn't worry too much about it as long as you arent seeing receeding tissue. Your water parameters look nice as well
