Sand stirrers

[Jared J]

Is there a good small fish to use to keep the sand stirred up in reef tanks? I know about the diamond goby but they get pretty big.

I feel like the diamond goby is one of the smallest sandsifters for a reef tank. other ones would include the tiger watchman goby. the sleeper gobies tend to get rather large and like to bring the sand up in the water making it obnoxious for corals on the sandbed.
