Jack o lantern leptoseris coral with white strings coming out

[fishy daddy]

Have had this jack-o-lantern coral for almost a week now, everything is good so far. A couple of days ago I started noticing slimy tentacle-like structures hanging from some coral areas, not sure if this is a normal behavioral/ feeding response or if my coral does need a light/ flow/ parameter adjustment.

It’s happy

Never had this kind of coral but i think its Sweeper tentacle. should be fine

Also know those will sting other corals so keep them at a distance

Mine exhibits those from time to time. Since it is fat and looks happy, I didn’t pay too much attention.
