If they get along or not does not depend on the variety of the discus. All chichlids tend to be teritorial as they mature and chose a mate. Young discus may get along fine until they mature. The same is true for other chiclids. As they mature things can get nasty. Discus arn't quite as nasty as most other chiclids. A bigger tank and places to hide will help some. Having a different tank or seperater is also a good idea. Don T.
