I was looking through my tank tonight. Happened to be looking along the substrate at the front. I saw a dozen or so little shrimp tunneling like ants. Anybody know what they could be? They were too small and jumpy to get a good picture of them. Only about 1mm long.

Then I spotted what looks like a centipede and bristle worm mixed that is no longer than an inch. I was able to get a decent pic of it.

The tunnelers are a common species of decapods, which look like bizarre tiny shrimp. They are part of the clean-up crew you get for free, and their tunneling (looking for eats) helps keep the sand fresh.

Okay cool. I saw them carrying little bits of stuff around.
