Unidentified Possible Food Source

Hi guys,

another question, I have my viv setup for about 3 months now, with no frogs. I'm seeing these small insects on the driftwood and wanted to ask if maybe you could help me identify what they are.

For lack of a digital camera, they're really small gray insects, somewhere about 1mm in length. They really look like springtails from all the pics that I see but they're gray. Or maybe they are springtails?

Would you have any idea what they are? They move around on the wet driftwood as I have a fountain feature. There's a possibility that they came with the moss bedding that I bought about a month ago.

Thanks
