These have been in my tank for a long time. Whenever I touch the sand they are evident, but always by the glass. I thought they were not alive, maybe left over food or something else, but when I move them they move right back within an hour. Makes my sand look like I don't take care of it and my nitrates are at 2.5 so they aren't rotting food. I've seen some move when I pull them out if I look close and hard enough.
