Trap door critter

[LgTas]

Cant say I've seen this before.

I've had this disappointing "sunset" psammacora frag for a while now (hoping it was going to colour up). It seems someone has decided to make a home in the top of it and has created a trap door which they peak out of while trailing a long slime line in the current. Would love to know what it is?
