Natural habitat

Dwarf Crayfish are found in slow-moving waters in warm conditions, typically in shallow areas rich with vegetation. This habitat provides safety and food sources for them, allowing them to thrive.

Where they are found

They are native to a volcanic crater lake, known for its relatively stable ecological conditions and unique biodiversity.

Aquarium care

For successful husbandry, maintain stable water parameters including a pH of 6-8 and a temperature between 18-25°C. Provide plenty of hiding spots with caves or driftwood, and ensure the substrate is soft enough for them to forage without damage. Regular water changes and a varied diet will enhance their health and coloration.

Feeding

These crayfish are omnivores and do well on sinking pellets, algae wafers, and protein-rich foods such as bloodworms and brine shrimp. It's important to avoid overfeeding, as excess food can deteriorate water quality.

Compatibility

While generally peaceful, they may prey on small shrimp, especially during their molts, making separate housing for dwarf shrimp recommended. Larger invertebrates, such as snails, can be safely kept together with CPOs.

Breeding

Mating does not require much intervention, but stable temperatures may encourage breeding. Females carry eggs and provide care until they hatch, after which, juveniles should be monitored to prevent cannibalism.
