Clean up crew suggestions for 20g

[AlyciaMarieee]

I'm looking for suggestions on what will be the best clean up crew for my 20g nano. I've acquired a few crabs that have made their way into my tank by hitchhiking on some coral, but that's all I have in there right now when it comes to clean up crews. I've heard from several sources that Nassarius snails are a good choice, but thought I'd get some more suggestions before I get anything. I'm not looking for any one type of invert, so I'm open to all suggestions! What have you found is the best clean up crew for your tank?

I can't keep snails alive in my tank. I do have Nassarius snails cruising around but most all other snails have died creating algae problems. 20g is small enough that you should be the only clean up crew in my opinion. Save yourself the trouble of dying snails.
