• Common Name: Tire Track Nerite Snail (also sometimes called Zebra Nerite, depending on the exact pattern)
• Adult Size: 2.5–3 cm (1–1.2 inches)
• Life Expectancy: 1 to 2 years in captivity

• Minimum Tank Size: 5 gallons (19 liters), more space preferred if keeping multiple snails
• Ideal Temperature: 22–28°C (72–82°F)
• pH Range: 7.0–8.5
• Water Hardness: 6–18 dGH (medium to hard water is ideal for shell health)
• Temperament: Extremely peaceful. Does not harm fish, plants, or invertebrates. An excellent addition to a peaceful community tanks.

Diet & Nutrition

• Omnivorous: Primarily herbivorous/algae eater.

  • Feeds mostly on biofilm, soft algae, and diatoms
  • Supplement with algae wafers, blanched vegetables (zucchini, spinach), or specially formulated snail food if natural algae is scarce

• Body: Usually dark grey to black with two small tentacles and a firm operculum ("trapdoor")
• Size: Up to 3 cm in diameter when fully grown

Distinctive Features

• Excellent Algae Control: Among the best algae-eating snails; effective on glass, rocks, and decorations
• Non-Reproductive in Freshwater: While they lay small white eggs, they do not hatch in freshwater, preventing overpopulation
• Operculum Protection: Closes tightly when threatened, providing excellent defense
• Escape Artist: Can climb out of the tank if the water line is too high or lid is not secure—ensure a tight-fitting cover
