Two Clownfish in EVO 13.5, one chasing the other

Any idea how to fix this? They seemed fine yesterday and today one of them is staying close to the top of the tank by the return to stay away from the other. I'd love for all of the fish to get along, any idea how to get it to stop chasing it?

Try putting a mirror in there.... Aggression between clowns is usually normal though. Part of the hierarchy.

If they are juveniles or an established pair then just wait clownfish can be real jerks to each other and most pairs are not all that peaceful. Some pairs only tolerate each other but never breed all you can do is wait. Having some hiding spots will help however.

How old are the fish? Clownfish are wired for hierarchy - in fact, whether they are female or male depends on it so aggression is often part of the process. This is not an unusual behavior nor should it be unexpected.

Okay, they are juveniles and have only been in the tank for 2 days and seemed to be getting along until today. Will this stop once the hierarchy is determined?

Usually after hierarchy is established then much of the aggression will stop with occasional flare ups and then may restart when they are ready to mate. Of course, since this is all part of the mystery and frustration of clownfish they don't always follow the rules.
