Red nose Shrimp Care Sheet (Caridina Gracilirostris)

Commonly known as Red Nose Shrimp or Pinocchio Shrimp (not all of them have a red nose!), this peculiar creature is characterized – you guessed it – by a large, rhino-shaped nose. Other less common names for this shrimp are, unsurprisingly, Rudolph Shrimp, Rhinoceros Shrimp, Needlenose Shrimp, Mosquito Shrimp and Rocket Shrimp (because these little fellas can swim FAST).

Pinocchio Shrimp main characteristics and behavior

Red nosed shrimp have a nearly completely transparent body with a pointy nose, usually of a vivid red color in males but not in females. Interesting fact: if the nose snaps off, these creatures are actually able to regenerate it. Please do not mutilate them on purpose.

Behaviorally, pinocchio shrimp are not much different from other caridinas: they get along well with other shrimp and will spend most of their time scavenging for food, and are particularly good at cleaning up your tank from algae and other plant matter. Because they are fast swimmers, it can be quite entertaining to just observe them move around your aquarium.

Ideal water conditions and environment

Because these shrimp originate from brackish water, they can be hard to keep in a freshwater aquarium. They will require some level of salinity and keeping an eye on your water parameters is a must if you decide to keep red nose shrimp in your tank. It is recommended to fill your tank with brackish water friendly vegetation such as bumblebee gobies and anubias. Keep in mind that these will also provide nutrition and hiding spots for your shrimp – something you shouldn’t take for granted.

Pinocchio shrimp breeding

Breeding pinocchio shrimp in freshwater is a nearly impossible task. We recommend moving your pets to a brackish water tank for the purpose of mating and so that the larvae can develop in an environment close to their natural habitat. It is especially important that red nose shrimplets have access to biofilm and microscopic food particles that can fit into their tiny mouths (check our instructions on how to take care of shrimplets).
