Black Kong Zebra Crayfish (Cherax sp)

Papua Black Crayfish

(Cherax sp.)

The Papua Black Crayfish is a bold and unique freshwater crayfish known for its deep black coloration and thick claws. Native to Papua, Indonesia, this species has a more natural, understated look compared to some of the brighter Cherax species, but its size, personality, and dark tones make it stand out in any aquarium setup.

Active and curious, these crayfish spend much of their time exploring, digging, and rearranging their environment. They do best in tanks with plenty of hiding places and stable water conditions.
