Help with Chaetodon Declivis

Hi!

I am in a need for advice, what to do with my trio of Declivis. 5 months ago I got 3 specimens for my 125 gallon aquarium (48 x 30 x 20). First they got a long really well, then after some time two of them paired up and now they have been really aggressive towards the third one, which is also the smallest one.

I have been thinking of removing the smallest one, but then I would have the tear down the big rockwork I have. Or Should I wait until I add more fishes to the tank and see if that alleviates the aggression down? One option is to get a 4th Declivis, if that would help...

Really need some advice with this :)
 
I would simply remove the third one. Use a fish trap.

Thanks for the input. Just spend 3 hours taking the rocks out and finally catch her. Shame they don't get along anymore, but I still have a beautiful declivis pair :) You never know with these guys :spin2:
