Aquatic Arts 1 Brazos Dwarf Crayfish/Mini Lobster (Cambarellus texanus) - 1/2 Inch to 1 1/2 Inches This miniature freshwater crayfish features a marbled pattern of various brown, tan, and beige colors. These do not hide during light hours like most crayfish - they are very active and mobile. They are also peaceful and do well in most community tanks, though they occasionally have been known to make a meal of dwarf shrimp. We keep them in a tank with guppies and live plants, and they never bother any of their tank mates. Easy to care for - the Brazos Dwarf Crayfish feeds on leftover food or almost any kind of fish food. All Aquatic Arts (formerly InvertObsession) brand plants and animals come with a 100% live arrival guarantee, plus free email support directly from the owners!
