Aquatic Arts 5 Live Freshwater Neon Yellow Shrimp (Neocaridina davidi - 1/2 to 1 Inch Long) Extremely bright and striking yellow color. These are breeding age young adults that will breed in a home freshwater aquarium. They range from 1/2 to 1 inch in length. In aquariums without much algae or biofilm, these shrimp should be fed high quality flake and mini pellet dry foods with high algae / spirulina / plant content. Dwarf shrimp are very small and are not ideal for aquariums with medium to large-sized fish. Please research dwarf shrimp before purchasing to ensure compatibility with your tank's inhabitants.
