About
Gracidina gracilirostris is an atyid shrimp of brackish water ranging from Japan and Fiji through Indonesia to Madagascar. SeaLifeBase treats it as a benthic species of fresh and brackish water, and it lives in mangroves and marshes feeding on algae. The body is nearly transparent, and the long red rostrum projecting from the head is its defining feature, carrying small tight spines beneath and larger, more scattered ones above; it regrows if broken off. Males show red lines along the flanks while females are paler and more transparent, and both have a distinct hump on the abdomen. Adults reach 3.5-4cm. It is peaceful and coexists with shrimp of similar size. Breeding is difficult because it mates only in brackish water and the larvae need brackish water to develop. Gravid females carry large numbers of green eggs. It is not listed by CITES.
