It has nothing to do with your snails or with the Viviparus genus either. Malleatus is a subspecies or species epithet to a different species in the Cipangopaludina genus. By that I mean Viviparus is a valid genus within the family, but not the right genus for these snails. They’re often labeled in the hobby as Viviparus malleatus, but that’s not a real species and takes elements of different genera and subspecies from other taxon within the same family (Viviparidae). “Japanese trapdoor” is a name used in the aquarium hobby only, for what are likely Japanese mystery snails (Cipangopaludina japonica). Snail expert Matt Reinbold gives us the breakdown: Mystery snails have a more rounded shell shape and fewer whorls (3-4) which are smaller and more compressed together. The bottom line? Overpopulation is not really an issue with these guys.įun fact: Babies often pop up after snails have been shipped, so keep an eye out after getting your new snails for youngsters in your fish tank! They may be eaten by bigger fish if you do not separate them.Ī post shared by Kira King is the difference between the JTS and the Mystery Snail? There are many distinctions, but the main one is easy to spot right away: The shell shape. It has 6-7 whorls with a taller, longer spire shaped like an ice cream cone. Tank-born babies are usually born brown or whitish and remain brown for the rest of their lives. They are super cute and grow relatively slowly, especially in cooler temperatures. Sexing can be done by looking at the shape of the snail’s antennae – the female’s tentacles point forward and are even while the male’s right tentacle is larger, shorter, thicker and points to the right as it is slightly curled under ( source). Get this: females then have a 9 month gestation period. So you have to wait 9 months after they mate for her to give birth! Unlike Malaysian Trumpet snails, this slow breeding process really helps curb an overpopulation problem like with some “pest” snail varieties. When the female gives birth she lays about 6-20 eggs in one go. She carefully removes the membrane to release the baby. They are also either male or female (non-hermaphroditic), not both at the same time. ![]() They don’t lay eggs. Eggs can be unsightly and annoying to remove, +1 to the JTS, -1 to the Nerite snail… sorry Nerites. Similar to Malaysian Trumpet snails, Japanese Trapdoor snails are livebearers. I bought my Japanese Trapdoors online here. None of them died in transit, and they acclimated very quickly. Each one is so different and unique, but beautiful! I recommend buying them online (like me) if you can’t get them locally.
