What's the matter with the blue shell of South American prawn? How to prevent it
The body color of normal shrimp is related to environmental conditions. In a pond with clear water quality or shallow water level, the body color of shrimp is often darker than that of shrimp with thick water or deep water level. Compared with the green of normal shrimp, unhealthy shrimp often appears blue. Blue may also be caused by heredity or bait, and normal shrimp will appear blue soon after molting.

Analyze the specific situation to see if your shrimp is normal or abnormal. If there are no diseased shrimps, it is suggested to use quick supplement 100 to supplement calcium and trace elements.
