Did you breed this fish or know the breeder? If not, there's no way you can say "For Sure"....while I agree with you it looks Trimac, you're merely guessing.Trimac for sure, and a nice one at that.
^Agreed.+1, Looks like a nice trimac to me but since you aren't sure you can refer to it as trimac but cant breed it and sell its fry as pure trimacs, as long as your not breeding though it doesnt really matter, the reason is that a lot of really low grade flowerhorns can look just like trimacs but actually have something else in their bloodline
