Aquarium color shrimp, such as Neocaridina and Caridina species, have become increasingly popular due to their stunning hues and patterns. These colors are not just aesthetic; they are deeply rooted in genetics. Understanding shrimp genetics can help hobbyists selectively breed shrimp with desired traits and maintain the health of their shrimp populations.
Color traits in shrimp are determined by genes passed from parent to offspring. These genes influence the pigmentation and patterns on the shrimp’s exoskeleton. Key factors include:
Different genes are responsible for the vibrant colors and patterns seen in popular aquarium shrimp species:
