Natural habitat

Procambarus milleri is a troglobitic species adapted to life in the subterranean karst habitats of the Miami Oolite formation. This crayfish thrives within shallow freshwater aquifers that are crucial for maintaining its ecological niche. Nutrients filter into the aquifers from surface vegetation, which supports the food chain necessary for its survival.

Where they are found

This species is endemic to Florida, primarily found within a narrow range of approximately 30 km x 7 km in Miami-Dade County. Most specimens have been collected from wells that access the aquifer, suggesting a limited distribution tightly linked to the aquifer's environmental conditions.

Aquarium care

To keep Miami Cave Crayfish in an aquarium, it’s vital to simulate their natural habitat with a low-light environment, gentle filtration, and stable water parameters. Ensure the tank is adequately covered to prevent escapes, as these crayfish are known to be good climbers. Regular monitoring of the water quality is necessary for the health of the species.

Feeding

Diet-wise, this species is omnivorous and will consume both plant matter and detritus. In captivity, a varied diet featuring high-quality sinking pellets, blanched vegetables, and occasional protein sources is recommended.

Compatibility

Miami Cave Crayfish are generally peaceful but can be territorial during breeding periods. They can be kept with other small, non-aggressive freshwater species, but care should be taken to ensure they aren't outcompeted for food.

Breeding

Reproductive behavior can occur year-round in captivity under stable conditions. Mating typically requires specific water parameters and a safe environment. Female crayfish will carry fertilized eggs until they hatch, requiring attention during this period to avoid predation from other tank inhabitants.
