Baby Anemone? Hydroid? Coral?

I've got a doozy for everyone this afternoon:

Any ideas? It appeared right after I got done scraping the glass.

This is not an answer because I'm not really qualified, but looks like what I was told was a hydroid.

More specifically, a hydroid jelly. They're usually short-lived in reef aquariums because we simply keep our tanks too clean.

Medusa stage hydroid. Some become nuisances but most are harmless. Should be fine!
