Tiny Moving White Dots On Glass

[Clarousel]

Hi all,

when I turned on the light of my tank today I noticed many tiny white spots on my glass in clusters and they're moving. They're so tiny I have to look very closely to notice.

Does anyone have any idea what they may be? They're slightly long-ish with a max of 1mm. I hope they're not parasitic It's giving me goosebumps!

Pictures would help, but planaria spring to mind immediately.

Very few things that grow in our tanks are worrisome.
Planaria does seem to fit your description.Or maybe water fleas.Both Harmless and a good natural food source for the fish or any fry.
Increased maintenance and a good cleaning of the substrate should clear em out quick enough.

My fish doesn't see them, or maybe he does but he doesn't bother? They're really tiny, like dust!

Sorry I'm not able to post a photo, rather busy and I doubt they'll be visible.

Well hopefully they aren't harmful Thanks for helping
