Hello. I bought two small red tiger oscars from petsmart back in september of 2011. They have been happily living in a 55 gallon tank ever since. The algae is starting to get uncontrollable and I would like to get some kind of algae eater. This is where I need your help. What will comfortably and safely live with my two oscars? I've heard that plecos get along with oscars but I would like to get this confirmed first. Thanks in advance
