Batman Snail (Neritina Auriculata)

Batman Snail (Neritina auriculata) — The Dark Knight of the Planted Aquarium

The Batman Snail (Neritina auriculata) is a striking and highly distinctive nerite snail named for its bold, dark shell patterning that evokes the iconic bat symbol. With its glossy, deep-coloured shell marked with dramatic black patterns on a dark base, this snail is as visually impressive as it is practically useful — a tireless algae grazer that keeps aquarium glass, rocks, and hardscape spotlessly clean without ever touching your plants.

Style and Function in One Shell

The Batman Snail combines the best qualities of the nerite family — exceptional algae-eating ability, plant safety, and no freshwater breeding — with a shell pattern that is genuinely eye-catching. Its bold, graphic markings make it one of the most decorative snail species available, adding visual interest to the substrate and hardscape while quietly performing one of the most valuable services in the planted aquarium: keeping algae under control.

Care Profile

• Scientific Name: Neritina auriculata
• Origin: Southeast Asia — brackish estuaries, rivers, and coastal streams
• Size: Up to 2–2.5 cm
• Temperament: Completely peaceful; safe with all fish, shrimp, and plants
• Diet: Algae grazer — feeds on film algae, green spot algae, diatoms, and biofilm on glass, rocks, and hardscape; does not eat healthy plant tissue
• Water Temperature: 22–28°C
• pH: 7.0–8.5 (requires hard, alkaline water to maintain shell integrity; avoid soft or acidic water)
• Tank Size: Suitable for any size aquarium from 20L upward
• Breeding: Will not breed in freshwater — larvae require brackish or marine conditions to develop, making population control effortless
• Note: Ensure the aquarium has a secure lid — nerite snails are known escape artists and may attempt to leave the water

Aquascape Compatibility

The Batman Snail is fully plant-safe and an ideal companion for shrimp — Neocaridina, Caridina, and Amano shrimp all coexist peacefully with nerites. It thrives in planted aquariums, hardscape-focused aquascapes, and community tanks alike, working methodically across every surface to keep algae in check. A practical, beautiful, and low-maintenance addition to any freshwater setup.

Bold in pattern, tireless in purpose — the Batman Snail is the dark knight your planted aquarium deserves.
