Black Devil Snail Care Guide
Faunus ater · Freshwater Invert

What Black Devil Snail look like
The Black Devil Snail, scientifically known as Faunus ater, exhibits a strikingly unique morphology characterized by its elongated, sharply pointed, and perfectly smooth shell that takes on a jet-black glossy appearance. This conical shell can reach a maximum adult size of 5 to 15 centimeters, providing a robust defensive adaptation against predators. The foot of the snail is grey to black, contrasting with the shell and enhancing its overall visual appeal. Notably, the absence of spiraled ridges on the shell distinguishes it from similar species, while a well-developed operculum serves as an additional protective feature. The shell's structure allows for efficient locomotion across various substrates, making it adept at navigating its natural habitat.
Behavior & temperament
Faunus ater is primarily a benthic organism, often found in freshwater environments across Southeast Asia. It exhibits a solitary lifestyle, though it may occasionally be observed in loose aggregations in favorable conditions. This species is not an obligate schooler and does not display a defined social hierarchy. Breeding behavior is characterized by egg scattering, with females laying eggs on submerged surfaces. The temperament of the Black Devil Snail is generally peaceful, although it may exhibit territoriality when competing for resources such as food or habitat.
Diet & feeding
In the wild, the Black Devil Snail is an omnivore, feeding on a diverse diet that includes detritus, algae, and decaying plant matter. In captivity, it requires a varied diet that includes high-quality algae wafers, blanched vegetables, and occasional protein sources such as shrimp pellets to ensure optimal health and growth.
