Aquatic Arts 1 Male/Female Pair of White Specter Crayfish/Freshwater Lobsters (2+ inch Young Adult) Caution should be exercised when keeping large crayfish: the rule is, if it can catch it, it will try to eat it. May breed with each other in home freshwater aquariums! They ship out as 2 inch long young adults that will grow up to 5 to 6 inches long. The exotic white coloring will surely make these beautiful animals the centerpiece of your aquarium! As with all of our crayfish, the coloration of the White Specter crayfish is extremely high quality. All Aquatic Arts (formerly InvertObsession) brand plants and animals come with a 100% live arrival guarantee, plus free email support directly from the owners!
