In either a 30 gallon or 100 gallon tank?

Depends on what you want them to do.

Do you want something to eat gunk?

Eat detritus. What else does a cleanup crew do?

There are various gobies that eat detritous but I think they are all sand sifters.

Lawnmower Blennies eat just about all types of green algae.
