It depends...parrots have different personalities due to the fact that they are a hybrid.
If you are thinking about putting one in your 75 gallon i would say no. You are going to be overstocked when the fish you have are mature (if they are not already).
Isnt there a lot of aggression with those breeding pairs?
Ah well i wouldnt know really. My parrots are big softies who wouldnt do well with other large aggressive types!
