Intricate Black & Gold Maze-Like Pattern Every Individual Unique Cannot Breed in Freshwater Up to 4 Year Lifespan Continuous Algae Grazer Shrimp Safe Batik Nerite Snails (Neritina variegata) are a rare freshwater Nerite species from Indonesia named for their shell patterning, which closely resembles the intricate wax-resist dyeing technique of traditional Javanese batik textiles. The shell is covered in a complex, maze-like arrangement of black and gold tones -- swirling, branching lines and dots that vary dramatically between individuals, with some specimens displaying dense near-black shells with sparse gold markings and others showing bold, high-contrast gold-dominant patterns. The pattern is never repeated: every Batik Nerite is genuinely one of a kind. Shell colouration can shift subtly over time in response to changes in water parameters, making the snail a living, changing element of the aquascape. Long-lived for a Nerite species -- up to 4 years in well-maintained conditions. Cannot breed in freshwater. Effective continuous algae grazer. Fully safe with all shrimp. pH above 7.0 preferred for long-term shell health. Appearance The Batik Pattern Intricate maze-like black and gold shell pattern -- named after traditional Javanese batik textile art -- the shell surface of the Batik Nerite is covered in a complex, highly detailed arrangement of black lines, swirls, and dots against a gold or amber base, or conversely gold markings against a near-black ground, depending on the individual. The pattern has a handcrafted, textile-like quality that reads as genuinely ornate at close range -- the fine-scale detail of the markings is most apparent in good lighting and at close tank-viewing distance, where the pattern reveals a level of complexity not visible from further away. Every individual is unique -- no two Batik Nerites share the same shell pattern -- unlike Zebra Nerites whose striped pattern is broadly consistent between individuals, Batik Nerite shell patterning is highly variable. The distribution, density, scale, and contrast of the black and gold markings differs completely from snail to snail. Some individuals have small, dense markings that produce an almost black overall appearance; others have large, bold gold areas with fine black outlining. A group of three to five Batik Nerites in the same tank will all look noticeably different from one another. Pattern can shift subtly with changes in water parameters over time -- hobbyists have observed that the colour and pattern distribution of Batik Nerites can change gradually when the snail is moved to different water chemistry. New shell growth laid down under different conditions may show different proportions of gold and black than older growth, creating a visible transition along the shell whorls that records the snail's parameter history. This is a natural biological response and causes no harm to the snail. Up to 1 inch at maturity -- long-lived up to 4 years, among the longest-lived Nerite species -- Batik Nerites are small to mid-sized Nerites reaching approximately ¾ to 1 inch in shell diameter at maturity. Their lifespan of up to 4 years in well-maintained conditions is notably longer than many other Nerite species, making them a more lasting investment as display invertebrates. Behaviour & Care Algae Grazing & Husbandry Continuous broad-spectrum algae grazer -- effective on glass, hardscape, and plant surfaces -- Batik Nerites graze constantly across all tank surfaces, consuming soft green algae, brown diatom films, biofilm, and fine organic deposits. They are particularly effective at clearing the thin algae films that accumulate on glass panels and smooth hardscape. In a well-established tank with adequate algae and biofilm they require no supplemental feeding; in newer tanks supplement with algae wafers or blanched vegetables. Cannot breed in freshwater -- population completely stable -- like all Nerite species, Batik Nerites require brackish or marine water for larval development. Small white egg capsules may be deposited on hardscape, glass, and plant surfaces but will not hatch in freshwater. Population is fixed at whatever number you introduce. pH above 7.0 preferred for long-term shell integrity -- tolerates down to 6.5 but not recommended long-term -- the Batik Nerite can survive in mildly acidic water but shell erosion accelerates below pH 7.0, gradually degrading both the intricate patterning and the structural integrity of the shell. Maintain pH above 7.0 and GH 6+ for best long-term shell quality. Calcium supplementation is recommended particularly in softer water. Standard Neocaridina parameters are ideal. Not recommended for Caridina tanks with active substrate and pH below 6.5. Cover the tank -- Nerites climb and will exit through any gap -- Batik Nerites are active climbers and will leave the water through any opening in the tank lid or rim. Keep water line at least 5–7cm below the rim or use a tight-fitting cover. A snail found outside and returned promptly usually recovers. Stock 1 per 10L -- sensitive to elevated nitrates -- Nerite Snails are sensitive to high nitrate levels. Keep nitrates below 20 ppm with regular water changes. Fully safe with all Neocaridina, Caridina, and other snail species. Keeper's NoteThe Batik Nerite is one of the few freshwater snails where the shell itself is the point -- it is genuinely ornamental in a way that smooth-shelled or simply striped Nerites are not. A small group of three on a piece of dark driftwood, or scattered across pale sand, shows the individual patterning of each snail clearly and creates a display that rewards close observation. The combination of the intricate shell, the rarity of the species, and the up-to-4-year lifespan makes the Batik Nerite one of the best long-term display invertebrate investments in the freshwater hobby. 🐌 Browse more freshwater snailsExplore King Koopa Nerites, Sun Thorn Nerites, Mystery Snails, and more.
