Im in the process of switching my tank over to a planted with discus. I am having a problem with brown algae. I know I cant put any plecos in the tank as they will feed on the discus slime coat. I do not have discus in the tank yet as I am waiting to establish the plants first. Im looking for some suggestions as to what I can put with discus that will take care of the algae and do general cleaning. What about ottos? Any input would be greatly appreciated.
