Little white “bugs”

[OliveFish05]

Hi! I was doing a water change on my 10 gallon tank just now, which house my 3 adult Cory Hastatus and their 30 fry, and I noticed these little white “bugs” skidding around the glass and swimming through my tank. They are too small to get a picture but does anyone know what they COULD be? Pleaseeeeeeeeeeeeeeeee tell me they can’t harm my fry!

Do they look like this?

It would just depend on how big or small those are. If they are barely visible, then yes! I can see the camera lense in the reflection, so I am guessing they are pretty small!

The white things in Phoenix's picture are cyclops (copepods) and they grow to about 2mm long and tend to flick about.

Ohhhhhh ok. If that IS what it is, how do they begin “colonizing” (is that the right word) in a tank? Any idea how they may have gotten in my tank? Are they always present and flourish with excess food? Will they hurt my catfish? Or are they good?

probably came in on plants and don't normally cause problems to fish

Ok, thank you! After the water change I don’t see any! (Obviously I know they are still there though)
