feuding neigbour?

I have a problem with my paired occellaris clownfish, especialy a female, which seem to act aggresive to the yellowtail damsel, but not try to kill or hurt him, but rather be a boss, the pair would attack the damsel if a damsel swimming across the fish or eating in same spot as clown. The pair seem to treat the my damsel as minion as they sometime not allowed to eat in surface unless the the food are sink to the bottom, sometime, my yellowtail damsel are not allowed to roam in open area, only in the lower section in the tank and nearest a damsel hiding spot , the clown will leave my damsel alone in this point. Surprisely, my paired clown are more peaceful toward my other fish , bicolor dottyback and lawnmower blenny but treat my damsel very inequal.

Damsel fish is aggressive towards other damsel fish, clownfish is damsel too so that's why.

The same thing happened in my tank too but only in the first month of introducing the damsel into my tank. My damsel is a golden belly which prefer to stay at the bottom, only eat on the surface. Yellow tail occupies the same water column/level as clownfish do so that also adds to the problem.

How long have they been together in the tank? What size is your tank? When did you add them?

My tank is 20 gllon, my clownfish pair is my first edition in last 3 month, i just add my damsel one week after adding clown pair. Then dottyback is introduced after two week, and my last edition is in 24/5/2017 is lawnmower blenny, come with coral banded along with 2 LPS (fungia and torch) and 1 SPS (mantipora caprionis).

3 damsel in a 20 probably will not end well. The clowns will probably weed out the damsel. If you can return it or relocate it I would. It's just stress your tank doesn't need.
