What is this

[Davidl919]

I can't name it and really can't even explain it, So it's a good thing I got a pic of it. It's about the size of those glass flatworms. With what you see in the pics it also seems to have three antennas

They're a type of hydroid. Essentially harmless. Many people have reported them appearing in tanks only to disappear in a short while.

Has anyone had a different experience with them?
