A black blotch behind the gills is a characteristic of these tetras, as is the relatively transparent body—hence the “phantom” of their common name. They look elegant in a shoal, thanks in part to the tall dorsal fin, which is more prominent in males. Include floating plants in their tank to mimic their natural habitat.
