When breeding the black shell shrimps, you can feed them every 3-4 days. This will help them grow better. But if the cultivation of black shell is only for algae removal, then in the case of algae in the tank, it can not be fed. They can feed on algae themselves. If they are used to feeding shrimp food, they may not eat algae any more.
Black shell shrimp is omnivorous shrimp, can eat a lot of things. When raising them, they can be fed boiled spinach leaves or artificial shrimp food. They can also eat animal feed, so they can occasionally be fed frozen red worms or tubifics. However, before feeding animal feed, we should first disinfect the feed, so as not to carry bacteria and make the shrimp sick.
Black shell shrimp in the vast majority of cases will not eat aquatic plants, only after the leaves of aquatic plants rot, they may eat the rotten part. In addition, in the case of extreme lack of food, they may also eat a small amount of tender leaves of aquatic plants. Therefore, it is no problem to raise black shell shrimp in grass tanks, as long as they are provided with sufficient food, they will not eat aquatic plants.
