Help me identify white spots on glass

[SaltySmith]

Hi everyone! Last week, I had these white spots show up on the glass. After doing a water change and cleaning, they came back. They have what looks like a solid center with legs that flow in the water. I tried to get a picture, was hard for the camera to focus on.

Those are hydroids - they're common in new tanks, and they frequently go away on their own.

Critter Identification: Hydroid Jellyfish – First Time Fish Keeper

f you are seeing tiny star-like organisms on your glass, they are likely to be Hydroid Jellyfish. They sort of look like very small Aptasia, or a snowflake or even baby star fish, they are not really much bigger than the head of a pin (1-2mm max).

I still get them from time to time on my tanks that are over 10 years old no worries

Not typically - like I said, they usually go away on their own.
