Something to sift sand that won't jump out, or eat the microfauna?

[kwirky]

I'm contemplating putting sand back in my tank now that things are stable. Basically I miss the microfauna I had with sand, and I did like the look when it was clean.

What kinda animals are good at sifting sand that won't jump out of the tank, and won't eat the microfauna in the sand? Heard most starfish will eat the beneficial stuff in the sand. I also don't want to cover/uncover my tank every day to keep a blenny from jumping out. (suspended lighting, no hood)

Is there anything else out there I could use?

One person says they rake their sand, but that'd be yet ANOTHER regular task added to the list...
