Can you ID these creatures?

Hope someone can help me identify these creature's ...these photos are taken at 60x magnification. Image 1 is backlit on my microscope, Images 2 and 3 are from the tank wall @ 60x too.
I find them on all the glass walls. I clean the front with the magnet cleaner and there right back there sticking to the front glass instantly! ​

What are they?​

This is a 40 gallon marine reef tank with 25 pounds live rock, and 40 pounds of CaribSea araganite Seaflor and 15 pounds live sand, see my aquarium too here.​

 

They look like mantis shrimp larvae, the only other thing it could be is millions of baby aptasia.....j/k
Ive read and heard so much contradictory id that ive decided that they are little critters that live on my glass for short periods of time.

 

They look like harmless hydroids. I get them on my glass all of the time and have never seen any negative impact of them being around.

 

its a sea booger!!!!!!

Hydroids

 

I get them all the time too. They only last until I clean the glass, lol. I wouldnt worry about them, unless you get millions of them, he he.

 

Thanks for the help!

 

Hydroids or possibly small brittle or serpent stars(babies).

 

Wow those little buggers are small! How did you find them. I agree with everyone above me...from what I can tell they are either Hydriods or baby stars.
