They’re not normally aggressive if the group and the tank are both big enough.
Somethings’s not right. Coming out for a day after a water change suggests a water issue.
What are the pH and nitrates?
How much flow/aeration is there?

Ph 7.6
Amm 0
Nitrate about 80ppm but its always high, it comes out tap at 30/40ppm, just thought i had started using tropica specialised nutrition hmm

That has extra nitrate in it, it won't help.
