Looks like it to me. Although the orange part is throwing me off.

I have never seen on stuck on the glass only in holes in the LR

 

[beaker5]

I have one growing inside my skimmer. Go figure. These things are hardy!

 

[frederickk]

I have the same problem too. Also had a bit of hair algae. Isn't that weird?

Yep, it's aiptasia and it's not uncommon to see it grow on glass. Easier to get rid of that way.
