Hitchhiker ID?

I was cleaning my glass and found a few of these on the glass. Any thoughts?

It’s very interesting. Not sure what it is though

hydroids of some species, they often wax and wane in population

 

[BranchingHammer]

I agree with @king aiptasia. I had some in one of my nano tanks for a bit, but they eventually went away.

That’s what I’m thinking. It looks to be a hydriod jelly.

Appreciate the quick replies!

I have them sporadically in both tanks...sometimes many, sometimes just a few. They come right off with an algae scrubber.

In fresh water, a boom of hydroids is a sign of over feeding with meaty foods.

Right on the money. I feed a random mix Rods, LRS, Oyster feast almost daily.

Yes, like others have pointed out, these are hydroids. Medusa stage hydroids to be precise and they should not be much of an issue to your tank inhabitants. If you use a turkey baster or a pipette to blow them of the glass, you will see them move like a jellyfish.
