Neocaridina davidi kept in aquariums have a wide range of colors, mainly as a result of selective breeding, though wild N. davidi also exhibit color variation naturally. As most of these shrimp are half transparent, the color of N. davidi nearly always is a result of "blood" ("flesh", muscles etc.) coloration and "skin" (the chitin of the shell ...
The color of these eggs will depend on the variety of individual shrimp. The shape of the ovaries curtains across both sides of the shrimp, giving rise to the nickname "saddle". The presence of a "saddle" indicates a female has eggs in her ovaries and may be ready to mate. [5] Eggs of the Neocaridina zhanghjiajiensis shrimp
Neocaridina is a genus of atyid shrimp, containing 26 species as of March 2023. [ 2 ] [ 3 ] Members of the genus are distributed across East Asia [ 4 ] including China, Korea, Japan, and Taiwan. Like many other Atyid shrimps, they live in freshwater habitats.
Caridina serratirostris, a widespread freshwater species from the Indo-Pacific region Caridina dennerli, one of several species restricted to the Indonesian island of Sulawesi Caridina cantonensis is widely kept in aquariums and several color forms have been achieved through selective breeding
It is the most studied type of environmental sex determination (ESD). Some other conditions, e.g. density, pH, and environmental background color, are also observed to alter sex ratio, which could be classified either as temperature-dependent sex determination or temperature-dependent sex differentiation, depending on the involved mechanisms.

P. paludosus in a freshwater aquarium. Feeder shrimp, ghost shrimp, glass shrimp, grass shrimp, river shrimp or feeder prawns are generic names applied to inexpensive small, typically with a length of 1 to 3 cm (0.39 to 1.18 in), semi-transparent crustaceans commonly sold and fed as live prey to larger more aggressive fishes kept in aquariums.
Commonly occurring sexual dimorphisms such as size and color differences are energetically costly attributes that signal competitive breeding situations. [1] Many types of avian sexual selection have been identified; intersexual selection, also known as female choice; and intrasexual competition, where individuals of the more abundant sex ...
