What is all over my glass ?

Came home today and found these all over my glass??

Anyone know what this is? Should I be in panic?

Hydroids. Harmless. Here is an R2R link to a similar question.

+1 Medusa hydroids. Common in newer tanks. They typically go away on their own as the tank ages.

Every dip is different and kills different things. If a coral can survive a dip, many other things can survive as well. I wouldn’t worry too much about it. Also, you’ll probably have other hitchhikers come along eventually as well.
