Noticed white spots on glass

So I have seen my pods but now I see these white dots that look like stars or spiders but seem to move much idk what they are, some type of pod or what

 

I think they are hydroid. They ok, if not how do k getrid of them, and will gobies eat them

 

Hydroids are not a concern.

 

O ok but are they a food source for anythin?

 

Not that I'm aware of; however, unlike colonial hydroids, hydroid jellies are fairly short-lived in our tanks. Their demise won't cause any issues, either.

 

I wont wry about them then

 

Here are a couple of pics of hydroid medusae:





These critters generally bloom in response to an abundance of small, live food blooms such as copepod blooms, or when feeding BBS to your tank. As mentioned, they will die back once the food source is exhausted.

 

Oo ok so when my pods are they will go away cause ik I have them all over my glass.
