Scoly - Hand in tank = feeding response

[Clown2020]

So recently I got my first scaly a lovely bleeding apple shown below. I have noticed over the last week anytime I put my hand in the tank for matinance no matter the time of day the scaly goes into feeding mode and starts send out tenticles. Anyone else had this experience? this guy seams to be the only coral showing this behaviour, has it learnt to recognise me some how ?

No, my hands are in the tank every other day. The scoly only opens at night.
