Company for Rosellas
It is recommended that Rosella birds are not housed with other birds, and if you are getting a pair of Rosellas it is best to only keep one pair per aviary. If they are housed in the same aviary (or close by) they will become aggressive towards each other. If you have a female Rosella and you are thinking of breeding, it is best to only get one male as they will fight with each other over the female.
