The ?Red Cherry shrimp?, Neocaridina davidi is a small freshwater caridean shrimp living, originally, in various kinds of inland water bodies around Asian countries.This shrimp has reached several countries for ornamental use; however,basic information on the biology of the species is still scarce in the literature.Its early postembryonic development morphology has not yet been described. This paper focused onthe production and the development of early post-hatching stages of N. davidi, its malesecondary sexual features, observation of the gonads and the presence of females withembryos. The larval development of N. davidi was almost suppressed as noted by thepresence of relatively large-sized eggs, first stage hatching as adecapodid; and the tail fans were present only from the 2nd post-hatching stage. Abiological important consequence of the presence of this Red Cherry shrimp species inthe Neotropics is its potential release into nature, which could cause its rapid dispersion affecting populations of other indigenous caridean freshwater shrimps.
