Strange looking creature, need ID

[ladyshark]

Hello,

I just filled my tank with live rock from Tampa Bay Saltwater, and discovered a strange looking hitchhiker. I have attached a picture, but
it is not the best view and a little blurry, sorry.

I am thinking it may be a nudibranch, but not sure. I originally thought it was some sort of soft coral, like ricordia--little bumps that are pinkish and tan. Then I saw that the thing moved, and now the extensions out of one end.

Can someone help me ID?

Thanks in advance

Some kind of hitchhiking sea cucumber.

Looks like a filter feeder.

Yep, filter feeding cucumber. Harmless.
