Blue Mystery snails tend to get more yellow on the shell as they age. The blue tint comes from the dark foot showing through a clear shell. As the shell ages, it thickens, and becomes more opaque. Still - pretty but different as they age.
Snails are very hardy and can handle cold quite well, but they will die if the temperatures get much below 20 F. They will also not travel well if the box gets much above 90 F for too many hours.
Mystery Snail - Pomacea diffusa (formally P. bridgesii), these beautiful snails are an apple snail that come in several color varieties. We will be adding more color varieties in the future. The only plant we've seen them eat is duckweed - which they love. A really big one will grow to about 2.25" in diameter. They lay their eggs in a cluster just above the water line, so it's easy to control them. Just remove the clusters or keep the water to the top of the tank. Dark Striped Purple (DSP) have a dark foot with purple shell and purple stripes. The Light Striped Purple (LSP) have a light foot with purple shell and purple stripes. The foot color affects the way the shell base color appears and the shade of the purple. There is a fair amount of variation among the adults. The ivory apple snail has a light foot in a clear shell. Keep in mind that shell color changes as they grow. As it grows, the shell becomes thicker and less translucent. The pigments often deepen and change in hue. Large adults tend to have less bright colors (though not always) and shells with more imperfections.
