ThanksThey few times I've seen Tapajos orangeheads (which is what I assume you mean) over black sand, they seemed very dark and washed out. They certainly seem to be one of the species that looks better over lighter, natural sand.
I'm no expert on Guianacara (Bandits), but those two do appear to have different markings... question: the one with the mid-lateral spot, rather than the bar, does it have a black splotch on the first few rays of the dorsal, like the one that has the mid-lateral bar?Were both sold as bandits
I found this on Google - it may help.Were both sold as bandits
