Samurai Gourami
Sphaerichthys vaillanti
The Reverse-Dimorphism Ghost (2.5 inches / 6 cm). The Samurai Gourami is an ultra-rare, ghostly, blade-shaped labyrinth fish from the heart of the Borneo jungle. It is incredibly famous among elite hobbyists for two reasons: its insane fragility, and the fact that the FEMALES are the brightly colored ones. When ready to breed, the female explodes into a mesmerizing zebra-striped 'Samurai Armor' pattern of deep blood-red and emerald green, while the male remains a dull, dusty brown leaf color. Keeping them alive is a master-class challenge.
