I have a large 8 x 3ft aquarium with one 6 inch Oscar, a6 inch red vieja 18 inch arowana and Florida gar. I wanted to add a couple more cichlids because it looks empty but the Oscar and red vieja go nuts at any attempt, they were previously ok with Severums datnoids and green terrors.
Should I take out the cichlids and restart with all juveniles?
