Clown aggression

[Ipyloves]

How to know when its more than it should be?

 

[bubbgee]

When it is attacking smaller fish and the smaller ones start to starve.

 

[James M]

When you see ripped fins or looks beat up

 

[Tangdora]

Striking or swiping that cause lesions to the body or fins of the other fish. Or going out its way during feeding to attack. If another fish is more on its mind than food then that room for concern.
