Blue Mystery Snail (Pomacea diffusa)

Mystery snails lay their eggs above the waterline in a pale, waxy cluster stuck to the tank lid or glass — a habit that trips up a lot of first-time keepers who assume snail eggs belong underwater. The blue color form is one of the more vivid options in the lineup, and just as easy and low-maintenance as any other Pomacea diffusa.
