Something attached to my button polyp

[sigs19]

OK, I feel like I'm making daily posts looking for ID's now. Apologies.
I found this thing attached to my polyp. I can't tell if it's eating the white thing or vice versa. Just didn't know if I should intervene. Did a google search and couldn't find anything similar. Anyone seen this before?
Again, sorry for being such a newb.

You all have been an awesome help! :bowdown:

From the look of it, it looks like a amphipod curled up, or its molt.

I loaded the tank with Copepods and amphipods about 3 months ago. Guess they've gotten established. And have grown! LoL
Thanks!

Amphipod molt.
The polyp might be trying to eat it. So it is cleaning up after the cleanup crew :)
