Is the unknown in the shaded area on the bottom of the plug. Looks like aiptasia versus feather duster.

No it’s the thing in between the two polyps he has been moving around that frag and it kinda looks like a baby snail is it harmful

 

[Lovemyreef2015]

It's a collonista snail.

 

[Tahoe61]

Looks like it could be a harmless Collinista. Other less harmless alternative IDs could be a Sundial Snail, Zoanthid Eating Nudibranch?
