Visual? As in pure BCC Hypos? No. The "salmon" trait is a name given to the "hypos" produced by Rich and John at Salmonboa.com. That's all they are, Salmon=Hypos. The Salmon trait is just a name given to the Hypos that STEM from Panamanian bloodlines. Like Orangetail is the name given to most Hypos from PURE Panamanian Central American bloodlines. 99.9% of the Hypos or Salmons you see marketed are mixed from one of those two bloodlines. The Salmons are outcrossed enough to be legitimately given the name Colombian, but they are not 100% pure Colombian.
