i turned the return off to allow some new rock nems to settle in and within a few minutes i had twenty or so of these guys crawling over my glass. as soon as i turn the return pump back on and flow to the tank (no power heads as this is a nem tank), they all either got swooshed away with the flow or squirmed back into the substrate.
and here's a video of them squirming around on my glass:
