Fluorescent newcomer

Hi everyone,
Just noticed a something growing out of my sps, is it just a different coloured sps, or is it something else.
Please take a look at the pic and advise me what is could be.
Thanks in advance

Well that’s weird. Definitely will be tagging along.

It is at expelled polyp or tentacle from another coral or 'nem?
