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 ...
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.
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
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.

The Los Angeles Chargers, Cincinnati Bengals and LA Rams all won on Saturday to either seal a playoff ticket or keep their postseason hopes alive.
A represents the dominant allele for color (yellow), while a represents the recessive allele (green). If each plant has the genotype RrAa, and since the alleles for shape and color genes are independent, then they can produce four types of gametes with all possible combinations: RA, Ra, rA, and ra.
Reproduction is the completion of their life cycle with individuals dying after spawning season is complete. Breeding seasons varies depending on the temperature of the water. [8] A female shrimp is able to lay up to 85 eggs per clutch. [8]
