what's on this Bubble tip?

[daveonbass]

asking on behalf of someone else...they want to know what the circled stuff is on the nem. Thanks for any info. And no I have NO clue as to what the water paramas are and or what kind of equipment they have (lights, filtration...)

just a strange pic.

I have never seen this but go to Karens anemones website and maybe she can advise. She is an expert.
Good luck
