Aquatic Arts 1 B-Grade Orange CPO Dwarf Mexican Crayfish/Mini Lobster (Cambarellus patzcuarensis) - 1/2 Inch to 1 1/2 Inches This miniature freshwater crayfish has a beautiful and eye-catching fiery orange coloration that will add a burst of color to your tank! The coloration of these dwarf crayfish is EXTREMELY high quality - much higher quality than others on the market! 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. This listing is for a B-Grade crayfish, which means that the crayfish will be missing more than one limb. All Aquatic ArtsTM (formerly InvertObsessionTM) brand plants and animals come with a 100% live arrival guarantee, plus free email support directly from the owners!
