Red Claw Crab
Red claw crabs can survive in freshwater, however in order to thrive and reproduce these crabs will require brackish water (1-2 tbsp. of Marine Salt added per gallon of freshwater). These are tropical crabs, and prefer the water temperature between 75-80 °F (23.9-26.7 °C). The pH should be stable around 7.5 – 8.5. Male Red Claw Crabs tend to have larger, redder claws and are more brightly colored, whereas the females have smaller, darker claws. Males have a narrower flap on the underside, females have a wider flap. Non-aggressive, mid to top dwelling and fast-swimming fish, such as most tetras, guppies, and mollies could make suitable tank mates. Due to their opportunistic behavior, Red Claw Crabs tend to try to attack and eat slow moving, sick, or bottom dwelling fish. It is vital to make sure tank mates can tolerate similar environmental conditions.
