An Ivory Snail is an interesting freshwater aquarium snail to keep. Ivory Snails are becoming more popular, and are often readily available in pet stores these days. An Ivory Snail shell color is off-white, creamy and smooth in texture. Its body and foot color are also off-white, with orange spots accenting the top of its head and mouth. This interesting creamy white and orange color combination can really stand out against lush green plants, black substrate or a black background.
