White Helmet (Neritina sp.)

Clean, elegant, and incredibly useful — the White Helmet Snail (Neritina sp.) is a striking freshwater snail prized for its smooth, dome-shaped shell in pristine white to pale cream tones. Like all nerite-type snails, it is a highly effective algae grazer that keeps aquarium glass and surfaces spotless, all while adding a touch of understated elegance to any planted or community tank.

Overview

Appearance

The White Helmet Snail features a smooth, rounded shell in clean white to off-white tones, sometimes with subtle grey or cream patterning. Its helmet-like shape sits low and compact on surfaces as it grazes, giving it a tidy, polished appearance. Against dark substrates or green plants, the white shell creates a beautiful contrast that makes these snails a decorative as well as functional addition to any aquarium.

Water Parameters & Tank Setup

• Temperature: 72 – 82°F (22 – 28°C)
• pH: 7.0 – 8.0 (slightly alkaline water supports shell health)
• General Hardness (GH): 8 – 20 dGH
• Tank Size: Suitable for tanks from 5 gallons and up
• Lighting: Moderate — encourages algae growth for grazing
• Important: Keep the tank covered — nerite-type snails can climb out of open tanks

Diet & Feeding

• Primary diet: Algae on glass, rocks, driftwood, and plant leaves
• Supplemental feeding: Algae wafers and blanched vegetables (zucchini, spinach, cucumber)
• Shell health: Cuttlebone or crushed coral helps maintain strong shells in softer water

Compatibility & Tank Mates

Completely peaceful and compatible with virtually all aquarium inhabitants:

• All community fish
• Dwarf shrimp (Neocaridina, Caridina)
• Other snail species

Avoid housing with snail-eating species such as pufferfish, assassin snails, or loaches.

Breeding

Like all nerite-type snails, White Helmet Snails require brackish or saltwater conditions to successfully reproduce, so they will not overpopulate a freshwater aquarium. They may deposit small white eggs on hard surfaces, but these will not hatch in freshwater — making them a perfect, population-controlled algae cleaner.

The White Helmet Snail is a clean, elegant, and hardworking addition to any aquarium — a natural algae controller that brings a touch of minimalist beauty to your tank. Simple, effective, and always on the job.
