Sure there are, Shrimp would be my choice in smaller tanks along with snails.
Algae is most often result of too much light both in duration, and intensity.
Problem with using live creatures is once algae is gone, creatures often slowly starve.
If you have sufficient plant mass that is thriving,,then algae has harder time surviving, but too much light will encourage it .
