White Wizard Snail
Filopaludina martensi
Also known as White Wizard, Wizard Snail, White Ghost Wizard Snail, Martensi Snail
Animalia›Mollusca›Gastropoda›Architaenioglossa›Viviparidae
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
White pitting, thinning, or a chalky, dissolving look to the shell, especially near the apex
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
Snail stays withdrawn with the operculum slightly open, little movement or feeding
Test for ammonia/nitrite spikes and do 25% water changes; confirm temperature is in range and the tank is fully cycled
Starvation
Shrinking body, failure to emerge, slow or no movement in a very clean tank
Offer algae wafers, sinking pellets, and blanched vegetables; let some biofilm and detritus develop in newer tanks
Trematode / Parasite Load
Tiny specks on the foot, sluggishness, and reduced appetite (more common in wild-collected stock)
Quarantine new snails and keep water clean; most flukes are snail-specific, but quarantine prevents spreading hitchhikers
