Species: Red Devil Snail (Faunus ater)
The Red Devil Snail is a striking freshwater snail known for its long, spiral shell that ranges from deep red to orange tones. This unique and eye-catching species adds a bold visual element to aquariums while also helping keep surfaces clean by grazing on algae and biofilm. Peaceful and hardy, they are an excellent addition to community and planted tanks.
Red Devil Snails (Faunus ater) are elongated, trumpet-shaped snails with vibrant coloration that can vary from reddish-orange to darker hues depending on diet and environment. Their sleek, cone-shaped shells make them stand out compared to more common aquarium snails.
They are active scavengers and algae grazers, spending much of their time moving along glass, substrate, and décor in search of food. Unlike many pest snails, they do not reproduce in freshwater, making them easy to manage in aquariums.

Red Devil Snails are peaceful and compatible with a wide range of community fish and invertebrates. They are slow-moving and non-aggressive, making them ideal tank mates for shrimp and peaceful fish species. Avoid housing with snail-eating fish or aggressive species that may harm them.
Red Devil Snails require brackish water conditions to reproduce, so they will not overpopulate freshwater aquariums. They benefit from calcium-rich diets and stable water parameters to maintain strong, healthy shells. Their coloration can become more vibrant with proper nutrition and care.
