Baby Aptaisia?

[SE7ƎN]

Need help ID'ing this.

I had about 30 of these in my glass and backwall. At first I thought it was GHA, however, during cleaning, it was jelly-like and attached to the glass. Wiped the glass and tried to get all of it off with Polyfyl. Hoping it's not baby aptaisia. Thanks.

Thank you. After googling Hydroids, it appears that this is the case. Thank you.
