Aquatic Arts 10 Live Freshwater Dream Blue Velvet Shrimp (Neocaridina davidi) - Breeding Age Young Adults at 1/2 to 1 inch Long 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. We ship out young adults that range from 1/2 to 1 inch in length. Dwarf shrimp do not grow larger than 1.5 inches. Lower intensity lighting and dark substrate helps these shrimp achieve the brightest blues. Requirements for blue velvet shrimp are essentially the same as red cherry shrimp, and they are just as prolific.
