little brown bugs on tank glass

[JoeMan02]

Ello ya'll, I noticed a bunch of little tiny bug-like things crawling on the tank glass. Are these things harmful in any way? sorry that the picture is so blurry, they're really small!

 

p.s. they move really fast as well

flatworms or bugs?  Can't see much in the photo.

Well, can't say without a better picture, but if they're on the glass it's a good sign.  It means they aren't exclusively on your corals eating them.  

 

If they are also on your corals, then maybe it's not good.

Do they almost look like they have a shell? If you look really, really closely? Could be baby snail, could be something completely different, could be one of these:

 

I've found these on the glass, along the sandbed, recently on a coral that had just been fed (the coral is perfectly fine), etc:
