hmm its probally growing pains.
lola has a newbie in her territory and she has to get used to it that can take time.
scott has to choose if he likes the noise of fighting more than having another cage haha .... if you did separate them id say make sure the cages are right next to each other so they can touch if they want but have there own space.
also make sure you have two of everything in the cage .... mine used to fight like crazy when i first got them even though they were bonded... cuz i had only one of stuff and once i got two flower cups two of the same perch, two platforms, two of each toy or something very similiar then they stopped fighting and now dont mind sharing.
establishing the pecking order can be hard specially with females
