I can't tell what you're looking at in this pic - all I really see is a grey blob in the center and an orange and black thing on the side. I have no idea what either would be based on the picture though.I got Tampa Bay Saltwater package yesterday and found this. I am thinking cucumber but hasn't moved.
The green thing may be a sponge of some kind, but I'm not sure (some green sponges like this can include Halichondria corrugata and Suberites aurantiacus, though if it was the latter I would expect to see orangish coloration inside the openings). I also don't see anything I personally would think of as worm-like in the pics, but there is a pineapple sponge in your other picture there (pineapple sponges are harmless filter feeders common to new tanks that typically disappear on their own in time).
Sorry I can't be of more help, hopefully someone else who knows for sure will chime in for you.
Edit: just to add, the green thing may also be a macroalgae like a Codium sp. I'm really not sure.
It is a sponge. Place in low light, good flow. It can fluctuate from a dark olive green to a deep aqua green. It is alive.
