Every once in a while, you might stumble across what appears to be a dead shrimp in your aquarium. You see carcass slumped over on the bottom and immediacy assume that your $20 shrimp has kicked the bucket. But before you start freaking out, double check to see if the body is just the leftovers of a recent molting. As shrimp get larger, they completely shed their skin, which can look just like the shrimp itself. It retains its color so well that it fools so many people into thinking their shrimp died. After molting, the shrimp will usually hide for a few days while its new shell hardens, further adding to the idea that your shrimp has died.
