Tylomelania species mixed varieties

31 August 2026

230

Tylomelania snails, often known as Sulawesi snails, are striking freshwater gastropods prized for their unique, elongated shells and active, curious nature. This mixed group represents various color forms found within the genus. Due to the high diversity and frequent cross-breeding in the wild, exact species identification can be challenging, necessitating careful observation of their specific needs in captivity.

Taxonomy and Origin

These snails belong to the Pachychilidae family and originate from the ancient lake systems of Sulawesi, Indonesia. They are characterized by their tower-shaped shells and distinct, often brightly colored bodies. Because many species share similar morphological traits and occupy overlapping habitats, distinguishing between specific Tylomelania species is difficult without expert analysis.

Habitat and Environment

They require a stable, warm environment that mimics their native, alkaline lake waters. A sandy substrate is essential, as they enjoy burrowing. They are sensitive to fluctuations in water quality and require well-oxygenated water with a moderate current. Hard water is necessary to maintain their shell integrity and prevent erosion over time.

Diet and Feeding

Tylomelania are primarily detritivores and opportunistic scavengers. In the aquarium, they readily accept high-quality sinking pellets, blanched vegetables like zucchini or spinach, and organic debris. Providing a varied diet is crucial for their health. While they may graze on biofilm, they should not be relied upon as the sole cleaner for algae.

Plant Safety and Behavior

These snails are generally considered plant-safe, though they may occasionally nibble on soft or decaying plant tissue if they are not receiving sufficient supplementary food. They are peaceful inhabitants that do not bother fish. They are most active during the day, making them excellent display animals in a community aquarium.

Reproduction and Population Control

Tylomelania are gonochoristic, meaning they have distinct sexes, and they are livebearers. Females produce a single, fully developed offspring encased in a protective egg sac. Because the reproductive rate is very slow compared to other common aquarium snails, they are unlikely to become a pest, and population control is rarely necessary.

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.
Orange Track Racing Snail (Vittina semiconica)

The Orange Track racing snail, Vittina semiconica, is a freshwater nerite valued for algae grazing and its patterned orange shell. It is generally peaceful, plant-safe and suitable for established community aquariums. Identification from shell pattern alone can be difficult because several Vittina and related nerite species resemble one another, so the supplied trade name should be treated as provisional unless confirmed by a specialist examination.
Orange Rock Snail (Orange Tylomelania)

The Orange Rock Snail is a trade name commonly used for orange-bodied Tylomelania, a group of freshwater snails associated with Sulawesi. Its dark, strongly ridged shell contrasts with the bright orange foot and head. Exact species identification is uncertain from the trade name and photographs alone, so care should follow general Tylomelania requirements. These snails are peaceful, active mainly at night, and best kept in mature, warm, alkaline aquariums with stable mineral content.
Orange Red Ramshorn Snail (Planorbella duryi duryi)

The orange red ramshorn snail is a freshwater planorbid recognized by its flat, coiled shell and brightly colored body. Planorbella duryi duryi is associated with freshwater habitats in the southeastern United States, especially Florida, although aquarium specimens may be selectively bred and their exact locality is often unknown. It is generally peaceful, useful as a grazer and scavenger, and capable of reproducing quickly when food is abundant.
Midnight Lady Snail (Vittina sp.)

The Midnight Lady Snail is a dark, patterned nerite sold under the aquarium trade name Midnight Lady Schnecke. It is identified here as Vittina sp., because the exact species cannot be confirmed from the supplied name and photograph alone. These snails are generally peaceful algae grazers for mature freshwater aquariums, but successful breeding requires conditions that are not normally present in freshwater tanks.
Ivory Predatory Snail: Anentome helena

The ivory predatory snail, commonly sold as Clea helena, is a freshwater assassin snail from Southeast Asia. It has a strongly ribbed, ivory to yellow-brown shell and a mottled gray-brown body. This active carnivore hunts or scavenges other small snails and accepts meaty foods in aquaria. It is generally plant-safe, but its predatory diet and egg-laying reproduction require planning when keeping it with ornamental snails or maintaining a controlled population.
Hedgehog Snail (Brotia armata)

The hedgehog snail, Brotia armata, is a large freshwater pachychilid recognized by its strongly ridged, spiny shell. It is a grazing and scavenging snail rather than a dedicated algae-control species, and it needs mature aquariums with clean, oxygenated water and adequate mineral content. Identification from photographs can be uncertain because several Brotia species have similar shell forms, so locality information is useful when confirming specimens.
