Would Janitor Fish do well in a Home-Depot Pond? - picture: janitor fish

My family decided that our goldfish in a pond, set in the court a year ago. They have grown incredibly, but leave a lot of green material for the routine cleaning pond. My question is, therefore, that to do even the janitor fish in this pool? I can not imagine eating such things. Exactly, we are on the same page, the janitor fish's mouth at the surface or the floor ... Get the picture?
Thank you!
