What's up with my red scallop?

[Chiefmaster30]

This is all over the side of my tank on the inside glass beside my scallop. Any ideas what it is?

You can see it best in front of the gold paly's on the 2nd pic. It looks like little sperms stuck to the glass.

In the first image I see Spaghetti worm tentacles.
I am guessing Hydroids for the second image but the unknown is not in focus.

If you put a finger behind the glass near the stuff the camera will focus on the finger and the stuff because theyre at the same distance.

It looks like some type of hydroid. If you're feeding your clam correctly (I really, really hope you are) then you'll likely be seeing more filter feeders grow in your system. There's lots of interesting things that grow in with my filter feeders.
