Which strain of flowerhorn is this?

[SK13]

Can anyone please tell which strain of flowerhorn is this?

And please suggest ways to make its kok bigger and brighter.

Thanks.

I can't tell its real strain since too many kind out there and depend its genetic the kok might look better or just stay like its current stage. However, good diet and pristine water condition will help a lot.

Looks to be a red dragon, but just a guess. Color an Kok are almost 90% genetics. Like mentioned quality food and frequent water changes.
