Common Mistakes with Nerite Snail

✗

Putting them in a tank under 5 gallons

While 5 gallons is the minimum, nano tanks require more frequent water changes and leave less room for error. A slightly larger tank (10 gal) is much more forgiving.

✗

Skipping the quarantine period

Even healthy-looking fish can carry parasites or disease. Quarantine new Nerite Snail for 2–4 weeks in a separate tank before adding to your main aquarium.
