I use to breed Kamfla 10 yrs ago and that does not look like breeding behavior as a matter of fact i would say that is not breeding behavior. Notice the other fish staying away up top they want no part of that fight.
The others are hiding from me the ran up there when I walked in room. They have only been in tank for about 16 hours. So if you think they are not short flowerhorn they must be parrots or kilin,Kirin. I have had a SRD With huge kok I grew from baby 10" now and looks nothing like these. Just wondering if they are Kirin,kilin parrot or Flowerhorn since there are so many sold under false name.
As to what type of FH you have i have no idea so much new BS FH out now they have ruined a hybrid fish
