White Wizard Snail

Filopaludina martensi

Also known as White Wizard, Wizard Snail, White Ghost Wizard Snail, Martensi Snail

Animalia›Mollusca›Gastropoda›Architaenioglossa›Viviparidae

Kept by 1 member in 1 tank

A peaceful, cold-tolerant cleaner snail that both grazes biofilm and algae and filter-feeds micro-organisms straight from the water column. Hardy, plant-safe, and a livebearer — it broods young inside the shell and releases tiny, fully formed snails.

Care

Diet

White Wizard Snails are peaceful detritivores and, unusually for aquarium snails, also filter-feed — using their gills to trap micro-organisms suspended in the water column. They graze biofilm, soft algae, and leftover food from surfaces and substrate, and readily take sinking pellets, algae wafers, and blanched vegetables. They leave healthy live plants alone, so extra feeding is only needed in very clean or newly set-up tanks.

Behavior

Calm, slow-moving bottom-dwellers, they spend the day plowing the substrate and grazing surfaces, often burrowing partway into sand to sift for food. They are completely peaceful toward tank mates and plants and tolerate a wide temperature range, which makes them suitable for unheated tanks and ponds. Stable, calcium-rich water keeps their shell and operculum in good condition.

Breeding

Unlike egg-laying mystery and apple snails, White Wizard Snails are livebearers (viviparous): females brood eggs internally and release fully formed juveniles, so there are no egg clutches above the waterline. They breed readily in a stable, mature tank with good food and adequate calcium, but don't overrun a tank the way some snails do. Sexes are separate, so keeping a small group improves the odds of reproduction.

Common diseases 4Shell Erosion / Pitting, Lethargy / Operculum Gaping, Starvation, Trematode / Parasite Load

Shell Erosion / Pitting

Symptoms

White pitting, thinning, or a chalky, dissolving look to the shell, especially near the apex

Treatment

Raise calcium and hold pH 7.0–8.0 with stable hardness; add cuttlebone or crushed coral and avoid soft, acidic water

Lethargy / Operculum Gaping

Symptoms

Snail stays withdrawn with the operculum slightly open, little movement or feeding

Treatment

Test for ammonia/nitrite spikes and do 25% water changes; confirm temperature is in range and the tank is fully cycled

Starvation

Symptoms

Shrinking body, failure to emerge, slow or no movement in a very clean tank

Treatment

Offer algae wafers, sinking pellets, and blanched vegetables; let some biofilm and detritus develop in newer tanks

Trematode / Parasite Load

Symptoms

Tiny specks on the foot, sluggishness, and reduced appetite (more common in wild-collected stock)

Treatment

Quarantine new snails and keep water clean; most flukes are snail-specific, but quarantine prevents spreading hitchhikers

Legality

No state or federal restrictions on record.

Not legal advice, and possibly incomplete or out of date. Rules vary by state and change over time; check with your state wildlife or agriculture agency before buying, keeping or shipping it.
