These shrimp are an excellent food source for just about everything you have. These are saltwater shrimp and will live and reproduce in saltwater. Many of these shrimp collected are carrying hundreds of eggs beneath their abdomens. These shrimp are not prolific breeders though. The baby shrimp feed tiny seahorses and mandarin fish. The adult shrimp are excellent food for Marine Bettas, Lionfish, or Anthias. They are used best to feed large fish. Great for feeding Sting Rays Octopi and Cuttle Fish.
