Please help identify. Little white creatures.

interestingly enough I just found this thread and I have this same problem now in one of my tanks, the little guys are every where attaching to my oscar and walking around on it, I see them walking around my slate and just as mentioned before they swim out of control. I have a major swarm too, rather weird little things.

That would make for a cool effect--if the people seeing it understood that these are not evil little critters, but a sign of a nice ecosystem within glass walls!

Uh oh. If you can see 'em and they're moving around on your fish it sounds less like microscopic mites and more like Argulus, the fishlouse. Try a www.google.com search, in IMG (image) mode, for Argulus.

They are too small to be able to tell, they are reeeeaally small, you have to look really hard to see them, so I can't tell, but when they are on my oscar I can see em, they've been in there for a couple weeks even after water changes and nothing bad has happened.
