Genus Hapalotremus

Andean dwarfs out of Peru, Bolivia and northern Argentina, and one of the most rapidly expanding genera in the hobby as new species get described out of that region.

Small, colorful in a way that surprises people who expect dwarfs to be drab, and adapted to high-altitude conditions. That last point matters: these are cool-climate animals and keeping them at the temperature most tropical species want is a genuine problem rather than a preference.

Most of what trades sits under sp. plus a locality name, because the description work is ongoing and the trade is ahead of it. Prices are firm on thin supply and there is real risk that two locality labels resolve into one species, which would collapse the premium on whichever name loses. Buy the animal, not the label.
