Hi. I have one juvenile oscar in a 125 gallon tank. I started with 2 juvenile oscars (both about 3 to 4 inches) but had to trade one in because he was beating up the one I kept. I am wondering if it would be wise to try other tank mates with the remaining oscar or if I should keep him alone. I have thought about adding a sun cat, chocolate cichlid, blue acara, severum, or a Trinidad or Sailfin pleco, or bichir. I am not saying I would add all of these. Only one additional fish or maybe two additional (i. e. a bottom feeder and another fish if I did add two). I am looking for something that won't beat up my oscar or be beat up by him and that won't get eaten or eat the oscar. What is your opinion? Thanks.
