They are not only delicious, but magnificent aquarium creatures with their large bodies, and round eyes on raised stalks. Pink shrimp burrow in the sand completely by day and dance in the water column by night, scavaging actively on whatever you throw in the tank. The diurnal white shrimp, Penaeus setiferus (or Litopenaeus setiferus if you must!) may be supplied when pinks are not available.
