Devil Faunus Lava Snail

The Devil Faunus Lava Snail is a striking freshwater snail known for its dark, almost black shell often accented with subtle reddish or lava-like streaks, giving it a dramatic appearance in aquariums. Hardy and adaptable, this snail is both an interesting display animal and a functional algae grazer, helping keep aquariums clean while adding visual texture to planted or community tanks.

This species is easy to moderate in care, thriving in well-maintained tanks with stable water conditions and plenty of surfaces to graze.

Care Requirements

• Tank Size: 10 gallons minimum

• Temperature: 22–28 °C

• pH: 6.5–8.0

• Water Hardness: Soft to moderately hard

• Diet: Herbivore/omnivore — algae, biofilm, blanched vegetables, and sinking snail foods

Behavior & Compatibility

Devil Faunus Lava Snails are peaceful and slow-moving, spending most of their time grazing on surfaces, rocks, and plants. They coexist well with:

• Peaceful community fish

• Corydoras and other non-aggressive bottom dwellers

• Shrimp

Avoid aggressive fish that may harass or eat snails.

Tank Setup

A planted aquarium with rocks, driftwood, and smooth surfaces is ideal. They enjoy grazing on biofilm and algae while having areas to retreat. Moderate water flow and stable parameters support their health and shell development.

A visually striking snail with dark, lava-streaked shell patterns—perfect for planted tanks and peaceful community aquariums while contributing to algae control.
