Who's your favourite (or not) sand sifter ?

[gregzz4]

Thanks to everyone for the input. It's nice to have all this info in one thread
You've narrowed down the list for me to gobies and/or just nassarius snails

Any more input on specific gobies would be great

Get some nassarius snails even if you get a goby. They move the sand but are very good at cleaning up any uneaten food. Plus if conditions are right they will reproduce. I put a dozen or so in my 70 gallon reef and there are now over a hundred babies.
