What is this on the glass??

[Cashby07]

Hey All!
Can anyone help? On the glass of my tank something is appearing... like small white dots with lots of short white thread like tenticles coming out of them. They're all close together in one area and dont move position. There seems to be more each day!
Anyone know what these are?

Many thanks!

Need a pic, but my guess would be hydroid jellyfish.

Do they look like this?

hydroids would be my guess too. They'll go away in time. (or when the mag float gets em!)

They are pretty much impossible to keep or propagate so not much to worry about
