Red Nose Shrimp (Caridina gracilirostris) is an intermediate-level freshwater invertebrate that needs at least 10 gallons and 72-82°F. A long, slim shrimp with a pointed red-orange snout that grazes algae and biofilm. It is often wild-collected and more delicate than cherry shrimp, and its larvae normally need brackish water, so do not expect it to breed in a freshwater tank.
