I'm not sure about this, still looking for real answers from somebody who knows a lot about Jags....but I THINK that "Honduran" Jags are black and white with a subdued gold tint on their body and blue in dorsal fins, and a bigger thicker barring in the black / white pattern.
The Nicaraguan Jags are a brighter white, with less or no gold tint in the body. They have a very fine/tiny black and white pattern on the body.
This is a picture from Mo Devlin of one of his "Honduran" Jags.

A Nicaraguan, is I think more like the one in the video below.
Now, if I could find one with the very fine black / white pattern like in that youtube clip, I'd buy a 180 today and grow some out--they're awesome. I just don't know what collection point to look for.
