Aquatic Arts 5 Live Freshwater Dream Blue Velvet Shrimp (Neocaridina davidi) - Breeding Age Adults at 1/2 to 1 Inch Long These shrimp are breeding age young adults that will breed in a home freshwater aquarium! They range from 1/2 to 1 inch in length. 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. Care requirements for blue velvet shrimp are essentially the same as red cherry shrimp, and they are just as prolific. All Aquatic Arts (formerly InvertObsession) brand plants and animals come with a 100% live arrival guarantee, plus free email support directly from the owners! Lower intensity lighting and dark substrate helps these shrimp achieve the brightest blues.
