Suggestion for good substrate sifter..

[Molino]

About 3 months ago I set up a 55 gallon SW tank and as of right now I have just 2 clownfish and 2 Pyjama Cardinalfish along with various corals (zoos,mushrooms,green polyps,xenia). I plan to also get a Lawnmower Blenny eventually, but would also like something interesting that will sift through the aragonite substrate, but not dig holes under the LR... The substrate is not sand, but it is fairly fine.

Some type of Goby I imagine would be best, but I'd like something that's not going to be hiding a lot and at least somewhat colourful.

In you experience do you have any good suggestions?

Thanks

a strawberry or spider conch would work well. My strawberry is constantly digging around, and I've yet to see him try and get under rocks in the year I've had him.
