Ghost shrimp are only as nutritional as the foods you feed them. Ghost shrimp are naturally low in nutritional value, but if you gut load them with the proper foods they can be. Feed high quality foods (best if frozen) and check the guaranteed analysis label to determine which food brands are most nutritional to each food type. Feed the ghost shrimp foods like algae wafers, bloodworms, shrimp pellets, catfish wafers, etc. etc. Ghost shrimp are scavengers, so it does not matter the types of foods, but more of the quality.
