Long-Fin Albino Corydoras

Take the standard albino cory's stripped-down pigment and add a long-fin trait selectively bred into the line, and you get trailing, almost veil-like fins that flutter as the fish forages — a look that has nothing to do with wild Corydoras and everything to do with decades of aquarium-strain selection. The core biology hasn't changed a bit: barbel-driven foraging, gut-assisted air gulping, and a hard preference for moving in a group.
