Our marine ghost shrimp (also commonly known as grass or marsh shrimp) make excellent live feeders and/or aesthetic additions to your home aquarium. Ghost shrimp are also excellent cleaners eating algae, detritus and uneaten food in your aquarium. Enriching your animal’s diet with live foods prompts them to behave more naturally than a diet of prepared foods. Our ghost shrimp reach a maximum of 1.5″ and are peacefully communal with one another when they are of similar size. They can tolerate salinity as low as 12 ppt. They are reef safe.
