Hi Mike,
The most commonly read advice for the Azureus is they do best in pairs as fighting is common when they are ADULTS.
Looks like you will be needing a few new tanks!
They will do fine in quarantine/type environment ( which is needed anyway ) . Paper towel sub.
I would suggest separating them!

providing a quarantine environment for ALL! for at least a month
The auratus will appreciate leaf litter ( boiled first ) to feel safe- as they are very shy!
It's nice to something for you........ for a change
