Pinocchio Shrimp Care Guide
Caridina gracilirostris · Freshwater Invert

What Pinocchio Shrimp look like
Caridina gracilirostris, commonly known as the Pinocchio Shrimp, exhibits a distinctive morphology characterized by its translucent yellowish body that can reach a maximum adult size of approximately 5-15 cm. This species is notable for its dramatically elongated rostrum, which is spike-like and colored red/orange, extending far beyond the head, providing a unique adaptation for foraging among algae and detritus. The shrimp's body is laterally compressed, allowing for agile movement through its aquatic environment. The presence of a well-defined carapace and a series of fine setae along the appendages enhances its ability to navigate through dense vegetation. Additionally, the Pinocchio Shrimp possesses a pair of prominent antennae and a fan-like tail (caudal fin) that aids in propulsion. Sexual dimorphism is subtle, with females generally being larger and more robust than males, particularly when carrying eggs, which are often visible through the transparent exoskeleton.
Behavior & temperament
The Pinocchio Shrimp is primarily a benthic organism, often found dwelling among the substrate and aquatic vegetation in its native habitats in India. It exhibits a social behavior typical of many shrimp species, often forming loose aggregations but not strict schools, allowing for both solitary and communal foraging. This species is generally peaceful and exhibits low aggression levels, making it suitable for community tanks. During breeding, females are known to be egg scatterers, releasing fertilized eggs into the water column, where they develop into free-swimming larvae. The Pinocchio Shrimp is also known for its scavenging behavior, actively seeking out detritus and algae, which it consumes in a methodical manner.
Diet & feeding
In the wild, Caridina gracilirostris is an omnivore, feeding primarily on algae, biofilm, and detritus. In captivity, it thrives on a varied diet that includes high-quality algae wafers, blanched vegetables, and specialized shrimp pellets to ensure optimal health and coloration.
