Singular Anemone tentacle bruised?

[reefers4life]

Hi everyone, I have this green bubble tip anemone and it split into 3. I tried rearranging them as they were all lumped together on 1 rock very close to each other (it was quite squeezy). As I did so today, I noticed that one of the anemone's tentacles had this on it. I'm not sure if its a bruise or something else. Can someone identify what it is and tell me how i can treat it? Thanks! I attached some pictures below for your reference.

No idea - are the colors accurate in the image? (seems very white)

yep in real life it's actually greener than in this picture. my camera just made it look whiter

I'm not entirely sure what to suggest. I have 3-4 green BTAs and I can't say that I've ever seen anything like this on the tentacles (all are doing their very best to remain inaccessible during the day - except to the clownfish).
