It's mostly genetic. You can feed him humpy head. But I think enjoying your fish is more important than having a fish which ranks better on certain irrelevant scale.Oh ... really..
Any recommendations can push up the head ??
Also see from pics lots of blue peral more than the red color
Is that going to change more red in the future ? Thanks heaps
ZZ is Zhen zhu and rd/srd is a type a type of Zhen zhu just as something like a Thai silk is a Zhen zhu. And I wouldn’t really label this fish any more than zz but you call it whatever you want. Although that is a desirable trait to some a flowerhorn can still be considered a super red dragon without a huge hump.Zz is red dragon. Srd means super red dragon, marketing term that means higher quality red dragon. Your fish though beautiful doesn't have big enough head to be srd.
