Red Nose Shrimp, also known as Caridina gracilirostris, are a freshwater shrimp species that are native to Taiwan. They are a relatively new addition to the aquarium hobby and are highly sought after for their striking red coloration and unique "nose" protrusion.
 
Red Nose Shrimp require specific water parameters to thrive, including a pH range of 6.5-7.5, a temperature range of 72-82°F, and moderately hard to hard water with a total dissolved solids (TDS) level of 200-400 ppm. They prefer a planted tank with hiding places and moderate water flow.
 
In terms of diet, Red Nose Shrimp are primarily algae eaters and will consume most types of algae in the aquarium. They may also benefit from supplemental feedings of commercial shrimp pellets, blanched vegetables, and live or frozen foods.
 
Red Nose Shrimp are peaceful and non-aggressive, making them suitable for community aquariums. They can also coexist with other types of shrimp, such as Cherry Shrimp or Crystal Red Shrimp. Red Nose Shrimp are relatively easy to breed, but may require specific water parameters and breeding conditions.
