Ok there are all kinds of fish that help control algae. Whats the best you have had experience with? Me, I would have to say out of all the assorted fish that thrive on algae, my pick would have to be the clown pleco, Panaque maccus . It is the only fish I have found that will clean a 55 spotless in a week or so. It will eat brown or green algae. Problem is when you have a 220 or so tank, it takes a few. I am looking for suggestions for a large tank, and a larger fish than a clown pleco., but one that does the job as well.
