funny you should mention that

Recently moved Oscar out of RDS house.. Oscar always teased RD and bullied him around... but nothing ever came of it and they always were together... but The RD finally got fed up with the Oscar and beat him up... nothing serious but enough that i knew it was time to move him... so now the Oscars are together again..doing fine so far and they are pretty equal now in size and other then flairing gills and open mouths they are okay together...if this does not work in the long term one will have to be in their own tank...
