hey everyone I am looking at the possibility of purchasing a pleco for my 220 but I don't know what is really out there. I am looking for a somewhat exotic pleco that maxes out at or around 12-14". I really like a certain royal pleco that is white instead of the normal green but I don't know how available these are. I have large carnivores in the tank but nothing real aggressive. I also have driftwood and plants in the tank. I seem to have a diatom algea problem that I can't get rid of so if there is a pleco that eats this it would be an added bonus. any help would be great. Here is a pic of my setup to help in the quest.
