White specks on glass?

[HandofThanatos]

Tank has been cycled for a couple months, started noticing these on my glass a couple weeks ago... tried looking stuff up about them but found mixed opinions on other peoples posts so I figured I would post here since everyone is so helpful!

I scrape them off every few days, but I notice them back on the glass within minutes.

Any idea what they are or if I need to genuinely worry about them?

Hydroids I believe

Yep hydroids. Nothing to worry about. They will vanish soon. I only ever see them when setting up a new tank.

look like hydroids to me

Ok cool, that is what I thought, but saw lots of varying levels of "they are fine" to "you need to restart the tank" I think the "restart" ones might have all been sea horse tanks though now that i think about it... hmmm...

Thanks again all!

Medusae hydroids. Not a problem except in breeding tanks.
