The mystery snail is not only just a single species of snail, however it is a large group of species that are commonly confused due to environmental conditions to look like other types of snails. Due to this large species being labeled as a specific type of snail, the term "mystery" was adopted since there is not a very accurate way to label their species in most cases. Apple snails are included inside of the mixture of mystery snails, and therefore you may have an apple snail instead of a mystery snail depending on the mature appearance and its specific traits. Mystery snail shells are generally brown in color, although in some cases white, cream, and even yellow have been reported as common traits. There can be various markings on the outside of the shell which can include patterns, stripes, color accents, and even other traits. The mystery snail's body can range from various colors including but not limited to grey, yellow, gold, blue, green, brown, purple, and even black.

These snails are non-aggressive and very peaceful by nature, which will feed off of algae, live plant matter, and excess food that gets left inside of the bottom of the tank or in spots where other inhabitants don't check. In most cases the mystery snail will be more active during the night when the lights are off due to predators being asleep during these hours. Since they mostly move during the night, making sure to have a tight closed lid on your aquarium will make sure that they do not easily escape between the cracks in the glass or plastic.


Breeding mystery snails is extremely easy as they will breed very commonly if the conditions are kept in prime settings. They will lay their egg sacks above the water line since these snails cannot breathe from the water itself, but rather need air from the surface in order to live. The egg sacks will appear to be white, yellow, or in some cases pink in color and will be spread out over an average area. If the eggs are kept humid but not fully submerged, they will hatch in approximately two to three weeks where the babies will fall into the water when hatching. It may appear that the babies will rock back and forth as they get used to their shell and new environment. No parental care is given to the babies once the eggs are laid, and the babies will start to eat algae until they are big enough to consume excess food from other sources.


Mystery snails will feed off of mostly algae that is covering the glass walls, on the substrate, on decorations, or even covering the leaves of life plants. In most cases they will feed off of any excess food that the other inhabitants don't eat or pick up after it has all settled down. Due to the snail not being a specific species, they may eat life plants fully while others will not touch them and only will eat the algae off of the leaves. Be careful if you have any slow growing plants since these snails may eat them fully before they have time to regrow leaves, steams, or more.
