White star-like growths on the glass

[blankminded]

I'm not sure if this is the right place to post this ever since I've been having an algae problem I'm starting to notice these small white things on the glass. I don't believe there moving but they have a small white dot in the middle and tons of little legs. Looks kinda like a star. I moved a 2 corals into a temp tank and over night there in the temp tank. I took some pics but there really tiny so the pics didn't come out to well.

The tank with a few of them on the glass

Close up of one...

Im just trying to figure out what they are and how to get rid of them.

Hydroids. These are in the free swimming jelly stage. I have never had issues and still occasionally have some on my glass. If they concern you, siphon them out using some airline tubing.

Yep, I have those too!

I have them in my tanks. It seems they are in a "Cycle" because I'll see them in all of my tanks (not connected) around the same time. Pretty cool IMHO.

Here are some I've captured with a camera

Thanks. I get lucky now and again. Plus I usually take hundreds when I take (1) LOL!
