Spixi Snail

Asolene spixi

📍 South America (Brazil, Paraguay, Argentina)

Asolene spixi, commonly known as the Spixi Snail, is an attractive freshwater snail native to South America with a distinctive spiral shell featuring dark coloration and intricate patterns. These peaceful grazers are excellent algae eaters and detritivores, making them valuable additions to planted and community tanks. They are relatively hardy and easy to care for, making them suitable for beginner aquarists.

Care Guide

Diet

Spixi Snails are primarily herbivorous and will graze on algae, biofilm, and decaying plant matter throughout the day. Supplement their diet with blanched vegetables such as zucchini, spinach, and lettuce. Provide calcium-rich foods and consider adding cuttlebone or calcium supplements to ensure proper shell development and prevent shell erosion.

Behavior

Spixi Snails are nocturnal and most active during evening and night hours, spending their days grazing on surfaces and hiding in plants or substrate. They are slow-moving bottom dwellers that rarely venture into the water column. These snails are generally solitary but can coexist peacefully with others of their kind.

Breeding

Spixi Snails are gonochoristic (separate sexes) and require both males and females to reproduce. They lay eggs in small clusters above the waterline on plants, hardscape, or tank walls. Eggs hatch into aquatic juveniles that develop in freshwater without requiring brackish conditions, so populations can increase rapidly in established tanks if not managed.

Common Diseases

Shell Erosion / Soft Shell

Symptoms

Shell becomes thin, pitted, or translucent; visible deterioration of shell structure; snail may appear lethargic

Treatment

Increase water hardness (GH) to 6+ dGH, add calcium supplements or cuttlebone, ensure pH is above 6.5, perform regular water changes, and provide calcium-rich foods like blanched spinach and algae wafers

Copper Toxicity

Symptoms

Lethargy, withdrawal into shell for extended periods, inability to move, death

Treatment

Immediately perform large water changes (50%+) to dilute copper, avoid all copper-based medications and fertilizers, use copper-free plant fertilizers, and check tap water source for copper contamination

Parasitic Infections (Flukes/Trematodes)

Symptoms

Excessive mucus production, shell damage, erratic behavior, refusal to eat, visible parasites on body

Treatment

Quarantine affected snails, perform daily 50% water changes, increase aeration, use snail-safe treatments like salt baths (1 tablespoon per gallon for 10-15 minutes), avoid copper-based treatments

Calcium Deficiency

Symptoms

Slow growth, weak shell formation, pitted or chalky shell appearance, reduced activity

Treatment

Add calcium supplements or cuttlebone to tank, increase water hardness through mineral supplements, provide calcium-rich foods, ensure pH remains stable above 6.5, and perform regular water changes with mineral-rich water
