Are my clowns breeding?

My clowns are staying in a cave in the tank. All my other fish including the cleaner shrimp will not leave their area. All the fish try to get into the clowns hosting area but the larger clown will chase them off. This has been going on for a few days.

I am hoping this is a temporary problem I don't like the aggression the clowns are showing. On a side note all fish have only been in the 240 gallon tank for about two weeks but until 3 days ago there was not a problem?

 

They might be maiting or could just be establishing there territory. My clarkii goes through this phase any time theres a major change in tank stocking, rock work or anything else.

 

Umm I see I guess that could be it. Do you think it will last long?

 

Mine never does unless its problems between clowns that seems to be a lasting problem.

 

Ok thanks I'll just watch them over the next week.
