New small black clown being chaced!

I have had two orange clown for just over a week. I added a small black clow today and they are chacing him everywhere! will they stop, or should I remove him?

 

Is there any nipping going on, and is the chasing pretty much constant or in spurts?

 

Has been pretty constant. Not sure if he's been nipped yet, but it's not from a lack of trying.

 

What size tank? Clowns can be VERY territorial, especially if the other two have already paired up. Keep an eye on it but taking him out might be a wise decision.

 

55 gal reef. I was afraid of that. Guy at LFS said it shouldn't be a problem but I wonder now..

 

In a tank that size it would be hit or miss at best if they coexisted peacefully. If it really does look like they are chasing/harassing it I would pull it, as it will probably only get worse.

 

In the past I've had clowns chase clowns, clowns chase damsels, and damsels chase damsels but without any harm brought to any of the fish being chased. It is usual for fish like these to chase ones lower in the hierarchy all the way down to the last Mohican, so I wouldn't personally worry unless fins actually got nipped or a victim was displaying signs of great stress. Just based on my experience, though -- Maybe someone else can give their experience and whether or not the chasing ended up being something that would cause them concern and what the end result was.
