Tentacle sweeping coral or something more sinister?

[ARTang]

Ive had this hammer coral for approx 4mos and this is the first time noticing this. Is this a feeding tentacle or something else? The only reason I question it might be something is else is because it doesnt look like any of the tentacles.

Thanks in advance.

Sweeper. Released to sting. Hammers can be aggressive. Is that a torch above it? Hammer and torch will attack each other, it might be too close

Right above it is a frammer.

should be ok with hammer. I think.

Regardless. What’s coming out appears to be a sweeper which means it’s stressed/scared/threatened/irritated/defensive. It should go away in a few hours
