Tylomelania Snail Care Guide

02 September 2026

589

Tylomelania snails, often called rabbit snails, are distinctive freshwater mollusks native to the ancient lake systems of Sulawesi, Indonesia. Known for their elongated, spiraled shells and expressive, trunk-like faces, these snails are popular among hobbyists. They thrive in stable, alkaline environments and require specialized care to maintain their health and shell integrity in home aquaria.

Taxonomy and Identification

These snails belong to the Pachychilidae family. Identifying specific species within the genus is notoriously difficult due to significant morphological variations. While often sold as a mix, they typically exhibit dark, spiraled shells with varying soft tissue colors, ranging from solid orange or yellow to spotted patterns. Due to the high number of undescribed species, precise identification remains uncertain.

Habitat Requirements

They require a mature, well-oxygenated aquarium with a soft substrate, such as fine sand, which mimics their natural lake bottom environment. They are sensitive to water quality fluctuations. Providing hard surfaces like rocks or driftwood is essential for their movement and grazing activities. A stable, alkaline water chemistry is critical for preventing shell erosion.

Feeding and Nutrition

Rabbit snails are omnivorous scavengers. They readily accept high-quality sinking pellets, blanched vegetables like zucchini or cucumber, and biofilm found on aquarium surfaces. To ensure healthy shell growth, calcium supplementation is highly recommended, especially in aquaria with soft water. They are generally peaceful and do not actively hunt other tank inhabitants.

Plant Safety

While generally considered safe for most aquarium plants, some individuals may consume soft-leaved or decaying vegetation if insufficient supplemental food is provided. It is best to keep them well-fed with vegetable-based foods to minimize the risk of them grazing on delicate aquatic plants.

Reproduction and Population Control

Tylomelania snails are gonochoristic, meaning they have distinct sexes. They are livebearers that produce very few offspring at a time. A female typically releases a single, fully developed juvenile enclosed in a protective white casing. Because of this slow reproductive rate, they are unlikely to overpopulate an aquarium, making them easy to manage without intensive population control measures.

Thunderbolt Snail (Tylomelania perfecta)

The Thunderbolt snail is a large, attractive freshwater gastropod associated with Sulawesi’s distinctive Tylomelania fauna. It has a long, heavy shell and a dark, strongly textured body, and it usually spends much of its time grazing surfaces or searching through the substrate. Aquarium specimens should receive stable, mineral-rich water, regular vegetable or prepared foods, and protection from copper-based medications. Trade identification can be difficult because several Tylomelania species and forms are sold under overlapping common names.
Staghorn Sun Snail (Clithon corona)

The Staghorn Sun Snail, Clithon corona, is a horned nerite from tropical Indo-Pacific waters. Its ridged shell and prominent projections make it distinctive, although shell color and horn development vary considerably. It grazes algae and biofilm from hard surfaces while generally leaving healthy plants alone. Adults can live in freshwater aquariums, but their marine or brackish larval stage means sustained captive breeding is uncommon. Identification from photographs alone can be uncertain because several Clithon and related nerite species have similar forms.
Swamp cover snail (Viviparus viviparus)

Viviparus viviparus is a temperate freshwater operculate snail associated with lakes, canals, ponds, and slow-flowing waters. It is a grazing and suspension-feeding species that consumes algae, fine organic particles, and other small food resources. The supplied photographs appear to show terrestrial snails rather than Viviparus viviparus, so they should not be used for identification. Aquarium specimens require cool, well-oxygenated water, adequate mineral availability, and careful feeding to prevent poor water quality.
Staghorn Snails Mix

Staghorn snails are a trade mix of small horned nerite snails, usually associated with Clithon species in the family Neritidae. The supplied images show several shell patterns and colors, so exact species identification is uncertain. They graze algae and biofilm from aquarium surfaces without normally damaging healthy plants. Adults may lay eggs in freshwater, but their larvae generally require brackish or marine conditions, making sustained freshwater breeding unlikely.
Red Widow Rennschnecke (Vittina waigiensis)

Vittina waigiensis is a nerite snail kept for its grazing activity and striking red shell forms. It is generally peaceful, plant-safe and suited to mature freshwater aquariums with stable, mineral-rich water. Like other amphidromous nerites, it may lay eggs in freshwater, but its larvae normally require brackish or marine conditions, so routine freshwater breeding is not expected. The trade name “Red Widow” may cover a selectively colored form rather than a formally recognized taxonomic variety.
Red racing snail (Vittina waigiensis)

The red racing snail, Vittina waigiensis, is a striking nerite kept mainly for grazing algae from aquarium glass, rocks and decor. Adults are generally peaceful, plant-safe and suited to mature freshwater aquariums, but successful captive breeding is uncommon because the larvae require different conditions from the adults. Shell colors and markings vary considerably, and trade names can overlap with other nerite species, so identification from appearance alone is not completely certain.
Mixed Aquarium Snails: Algae Eaters and Clean-Up Crew

This mixed snail selection appears to include nerite-type algae grazers, ramshorn snails, and possibly Malaysian trumpet snails. Exact species and proportions cannot be confirmed from the supplied images, so care requirements may differ between batches. These peaceful invertebrates consume algae, biofilm, leftover food, and detritus, but they still need stable, mineral-rich water and responsible population management.
Red and Yellow Stripe Rennschnecke (Vittina waigiensis)

Vittina waigiensis is a striking nerite snail recognized by a rounded shell with red, yellow, orange, and dark patterning. It is primarily a freshwater grazer as an adult but has a life cycle that normally requires brackish or marine conditions for larval development. This makes it suitable for planted aquariums without normally becoming numerous. The supplied trade name and images are consistent with this identification, although shell patterns overlap among Vittina and related nerite species, so visual identification should be treated as provisional.
Ramshorn Snails Mix Rainbow

Rainbow ramshorn snails are a mixed-color freshwater aquarium form sold under a trade name rather than a single precisely identified species. The pictured animals have the characteristic planispiral shell and include blue, pink, pale and orange-red forms. They are peaceful scavengers that graze on biofilm and leftover food. Exact species and strain lineage cannot be confirmed from the supplied images alone, so care guidance is provided for commonly kept aquarium ramshorn snails.
Predatory Snail: Clea helena (Anentome helena)

Clea helena, also widely sold under the name Anentome helena, is a freshwater predatory snail from Southeast Asia. Its banded, cone-shaped shell and active hunting behavior distinguish it from common algae-grazing snails. It feeds mainly on other snails but also accepts meaty foods and carrion. In a mature aquarium it is generally safe with healthy plants, although it can reduce or eliminate desirable snail populations. Identification and classification may vary between sources, so both commonly used scientific names are included.
Pointed Mud Snail (Lymnaea stagnalis)

Lymnaea stagnalis, commonly called the pointed mud snail or great pond snail, is a freshwater pulmonate snail found in quiet, vegetated waters. Its tall, pointed shell and ability to breathe atmospheric air make it distinctive in aquaria. It can be a useful scavenger, but it reproduces readily when food is abundant. The supplied images are broadly consistent with this species, although photographs alone cannot confirm identification with complete certainty.
Pond post horn snail (Planorbarius corneus)

Planorbarius corneus is a European freshwater ramshorn snail found in ponds, lakes, marshes and slow-moving waters. Its large, planispiral shell and dark body make it a distinctive aquarium inhabitant, although the common name can be confused with other ramshorn snails. It is generally peaceful, useful as a scavenger and algae grazer, and manageable when food supplies are controlled.
Pimpled Lace Snail (Melanoides granifera)

The pimpled lace snail, Melanoides granifera, is a burrowing freshwater snail from the family Thiaridae. It spends much of its time in substrate, emerging to graze on biofilm, detritus and leftover food. Its ridged, patterned shell adds interest to planted aquariums, while its live-bearing reproduction can gradually increase its numbers. It is generally peaceful and plant-safe when adequately fed, but should be kept under observation because identification and appearance can vary among imported aquarium stock.
Pink ramshorn snail (Planorbella duryi duryi)

The pink ramshorn snail is a freshwater planorbid recognized by its flat, coiled shell and pink to reddish body. The supplied name identifies it as Planorbella duryi duryi, a subspecies associated with the southeastern United States, although shell color alone cannot confirm an exact identification. It is peaceful, air-breathing, and useful as a scavenger in planted aquariums. Like many ramshorns, it can reproduce quickly when excess food and organic debris are available.
Piano Snail (Taia naticoides)

Taia naticoides is a freshwater, live-bearing snail sold under names such as piano snail. It has a rounded, banded shell and is valued as a grazer of algae and aquarium biofilm. The supplied photographs resemble this trade identification, but images alone cannot confirm species, age, or whether the specimen is a juvenile. Good calcium availability, stable alkaline water, and regular access to natural or supplemental food are important for long-term care.
Piano Snail (Taia naticoides)

The piano snail, also sold as the brush algae snail, is a large freshwater operculate snail with a rounded, banded shell. Taia naticoides is associated with Southeast Asian freshwater habitats and is valued for grazing surface growth and consuming organic debris. Aquarium identification can be complicated because common names are applied inconsistently; confirm the species with a reliable supplier. It is generally peaceful, plant-safe and live-bearing, but it needs mineral-rich water and should not be treated as a solution for heavy algae growth.
