Green chromis odd behavior. Breeding?

Hi all,

I've had my 6 Green chromis's (or is it Cromies) for about a year now. They have always been the life of the tank, schooling all the time. Lately they have been acting odd, they still eat well but they don't school anymore. They seem busy behind rocks, like they are having a meetings and plotting to take over, lol. I see also see a lot of tail fanning action.

Could they be getting ready to breed? If so, would that cause havoc to my reef and other fish?

thanks,
Ray
