My clownfish is breathing fast

[thor0469]

So long story short. I got two clowns about 2 and a half month ago, both juvenile. One bigger than the other. But anyway, the small one was apparently a lot more agressive than the bigger one, and now chace the big one around, it has grown and is only a little smaller than the big one now. Problem is, that the bigger one seems very tired of getting chased around, also lays on sandbed, breathing fast, sometimes he swims upto the surface just laying sideways and breathing fast.

Is this normal when clownfish establish a dominance relationship?

 

Just added picture of my nano reef!

btw its a 16 gallong tank, i have 3 fish, 2 clowns and a firefish, its been running for 5 months and, and i'm upgrading to a 30 gal to give the clowns more space!

I have a maroon clown and a misbar clown and the moroon clown likes to lay on his side alot and both are what Id cll 'breathing hard' ive has them both atleast six months and it seems pretty normal to me.

 

Does yours seem to sleep normal at night?

clowns are very weird. as long as they eat and otherwise look healthy, they should be fine.
