Water Fleas?? Please Help Identify These Little Critters

[jlcrow]

I have little white things hoping around on the bottom of one of my tanks. I think they might be water fleas, but I am unsure as they seem to be a lot bigger than the examples I have seen in pictures. Plus they are almost always on the bottom of the tank, not swimming around. I attach a screen capture from a video I took of them. I underline them because they kind of look like small pebbles. I also have a 20 second video, hosted on YouTube, that shows their behavior. I should also note that I have guppy fry and juvenile mollies in the tank and they are not eating these critters. I would appreciate someone confirming these are water fleas, or if not, please help identifying them.

Thank you for your time and assistance!

Looks like some kind of ostracod.

Ostracods. Nothing to worry about.

I have read that ostracods can pass through a fishes digestive system completely unharmed. Thus that may be the reason fish tend to avoid them 

 

But I third the ostracods ID

Thank you all for the identification!
