Regardless you have them in a 35 gallon to a 600 gallon to even perhaps 1000 gallon, it's only a matter of time before the aggression starts.
Once they reach that comfort zone and realize that they consider the whole tank their territory is when the bashing begins.
If you want a better success rate for a school of payara's that gets to a good size than redtails (Tat) are the way to go. You can see it from the get go where they like to stick together, where the ARMATUS is distant and prefers to keep to himself.
Again, we are all new Armatus keepers so only time will tell with others who has a few. But for those who has kept multiples is/have already experienced the aggression.
What's crazy is that ARMATUS is new in the states where in Japan they receive them on occasions. Hopefully a member from Japan who has had personal experience with them can interject and share some info.
