Raising Nerite Snails

Caring for nerite snails—some of the most popular and effective algae-eating snails in the freshwater aquarium hobby—is simple, rewarding, and perfect for beginners. Known for their striking shell patterns (zebra, tiger, horned, olive, etc.) and peaceful nature, nerite snails won’t overpopulate your tank (their eggs rarely hatch in freshwater) and are safe with plants, shrimp, and community fish.

🐌 1. Tank Setup & Size

• Minimum Tank Size: 5 gallons for 1–2 snails; add 2–3 gallons per additional snail.

• Lid: Essential! Nerites are climbers and will explore above the waterline.

• Substrate: Sand, fine gravel, or bare-bottom—no special requirements.

• Décor: Smooth rocks, driftwood, and live plants (they love grazing on hard surfaces like glass, hardscape, and broad leaves).

💡 Nerites spend most of their time on surfaces, not burrowing—so décor with lots of surface area is ideal.

💧 2. Water Parameters

Nerite snails thrive in clean, stable, alkaline, hard water—soft or acidic water dissolves their shells.

• Filtration: Standard aquarium filter is fine—no strong currents needed.

• Water Changes: 20–30% weekly with dechlorinated water.

• ⚠️ Never use copper-based medications—lethal to snails.

🛡️ Shell Tip: If you see white, pitted, or eroded shells, your water is too soft/acidic. Add crushed coral, cuttlebone, or use mineral-rich water.

🥬 3. Diet: Algae Experts (But Need More!)

Nerite snails are herbivores and excellent algae grazers, but they won’t survive on algae alone in clean tanks.

• Primary Food Sources:

  • Natural algae (diatoms, green spot algae, film algae)

  • Supplemental foods (essential in well-maintained tanks):

    • Algae wafers (sinking)

    • Blanched vegetables: zucchini, cucumber, spinach

    • Biofilm and aufwuchs on rocks and wood

• Calcium: Provide cuttlebone, crushed coral in filter, or liquid calcium to support shell health.

🕒 Feed at night or after lights out—they’re most active in dim light.

🧪 4. Breeding & Eggs

• Good news: Nerite snails won’t overpopulate your freshwater tank!

• Why? They require brackish or saltwater to hatch their eggs.

• Eggs: Laid as tiny white sesame-seed-like dots on glass, pipes, or décor.

  • Harmless but can be hard to remove (scrape with a razor blade on glass).

  • Won’t hatch in freshwater—so no baby snail explosion.

🌊 Fun fact: To raise babies, you’d need a separate brackish tank (SG 1.005–1.010)—not practical for most hobbyists.

🐟 5. Tank Mates & Compatibility

• Excellent with:

  • Peaceful community fish (tetras, rasboras, guppies, corydoras)

  • Shrimp (cherry, Amano, bamboo)

  • Other snails (mystery, ivory, rabbit—but not for pest control)

• Avoid:

  • Loaches, puffers, large cichlids, crayfish (they’ll eat or harass snails)

  • Overstocked or dirty tanks (nerites starve without algae/supplements)

🩺 6. Common Health Issues

• Dissolving or pitted shell: Caused by low pH/GH—test water and add minerals.

• Lethargy or inactivity: Could mean hunger, poor water quality, or old age.

• Flipped on back: They can usually right themselves—but help if stuck.

• White film or fuzz: Usually harmless biofilm; clean if excessive.

✅ 7. Benefits of Nerite Snails

• One of the best algae cleaners (especially for glass and hard surfaces)

• 100% plant-safe—never eat healthy plants

• Peaceful and non-invasive

• Eggs don’t hatch in freshwater = no overpopulation

• Visually striking and active during the day

With proper water chemistry and supplemental feeding, nerite snails will thrive while keeping your tank sparkling clean! 🌿🐌
