DSB Sand Sifter?

[Son Of Skyline]

I have a 2" long pistol shrimp who moves an incredible amount of sand on a daily basis. He's all i've ever needed to keep my sandbed clear. Best part is that he's not targeting sandbed critters. He just wants to keep maintaining, building, and expanding his burrow. Paired with my watchman goby, the shrimp is not shy at all and just shovels sand all day long.

Just food for thought but it works for me. If you do go with a pistol i suggest a larger one as i've seen little ones in other peoples' tanks and they just hide all day.
