What is an excellent 'bottom cleaner' that is pretty active?
(info added) This will be for a 5 gallon aquarium.
Thanks.

Whoops, I guess that I didn't see the 'for 5g' added information! For a 5g with active bottom feeders I would go with shrimp, they're not really at the bottom all of the time, but they are entertaining and fun to watch. Plus they get the scraps of food on the bottom that the fish did not eat!
