I don't have any experience with captive pumilio's but I can contribute with some pictures of the localities that are dicussed in this thread, that might be useful:
This is a Salt Creek with a tad on the back. At this locality on the east of Bastimentos there are individuals with dots like this one and without dots. However the ground color were consistent with red back and whitish belly. The legs were more or less grey with black pattern.
This is an "Old point" (Punta Vieja) individual. Basicallly they are more speckled with black and they have more grey on the legs. This seems to be a very small population and I would consider it to be very vulnerable to habitat destruction and other disturbances.
This Individual is from a Creek a couple of kilometers noth west. All individuals were totally red (most of them even on the belly). This coloration is present in big parts of inland eastern Bastimentos and I guess that in captivity these individuals are often mistaken for Cayo Nancy (Nancy Cay, Isla Solarte)
Cayo Nancy. In my point of view impossible to distinguish from eastern inland Bastimentos.
I hope that this has been to some help.
