My opinion is there is 3.
I havent seen anything regarding..het, morph, or percent head black bloods. So the heads are types and morphs are just morphs, if that make sence. Vpi has different morphs. Zebra, Caramel, etc...Carmel morph as been confirmed but not sure what type of gene.
The black heads are known to grow longer...
The orange/peach/yellow..(rare imo, nice clean one) smallest.
Chrome heads grow in between.
What ever your beliefs are is up to you regarding types or morphs. I tend to say 3 and morphs dont count. But thats me.
To me...Its like for the bloods for example. They have locales. Brongersmai, Bangka, and sumatra reds. Stripes, hypos, ya-di..ya da..are red morphs to me...
Just fyi. Kara can confirm the 3 types and their lengths...![]()
