* Natural aging: As queen palms prawns grow, their shells will naturally become thinner and more translucent, revealing the yellow color of their flesh.
* Diet: Queen palms prawns that eat a diet rich in carotenoids, such as astaxanthin, will have a more intense yellow color. Carotenoids are pigments that give plants and animals their red, orange, and yellow colors.
* Stress: Queen palms prawns that are stressed or diseased may also turn yellow. Stress can be caused by a variety of factors, including poor water quality, overcrowding, and temperature fluctuations.
If you are concerned about the yellow color of your queen palms prawns, it is best to consult with a veterinarian or aquatic specialist. They will be able to determine the cause of the yellowing and recommend the best course of treatment.
