Nicaraguans are mostly black and no where near as cool looking. They are a lot nippier and harder to tame than Columbians. I got bit on the friggin ear lobe by one of them! PmeOff bad. Myself I'd go with the Columbian, but if you want another idea check out the Guyuna Red Tails, they absolutely Rock! or a Surinam, they are cool too. I just bought two Columbian Albino Hets, wanna wait three years for an albino, LOL!
