Black Ramshorn Snail

A selectively bred Ramshorn with a deep black shell and dark body, combining the continuous grazing utility of the species with a colour that works equally well on light and dark substrates.

Deep Black Shell Dark Body Continuous Algae Grazer Self-Regulating Population Shrimp Safe Nano Tank Suitable

Black Ramshorn Snails are a colour-selected line of Ramshorn snail (Planorbarius corneus / Planorbella spp.) bred for a deep, near-opaque black shell and a uniformly dark body. The Wild Ramshorn's shell ranges from brown to reddish-brown; the Black Ramshorn has been selectively developed to express melanistic colouration across both the shell and body tissue, producing a snail that reads as genuinely black at tank-viewing distance rather than merely dark brown. The flat coiled shell profile and haemoglobin-based red-toned blood remain characteristic of the species, but the overall appearance is distinctly different from wild-type stock. Like all Ramshorns they are continuous, indiscriminate grazers that process biofilm, algae, decaying plant matter, and uneaten food. Population scales with food availability and is managed entirely through feeding discipline. Safe with all shrimp. GH 6+ for shell health.

What Makes the Black Ramshorn Distinct

Deep black shell bred through selective melanistic line development sets the Black Ramshorn apart from the brown and reddish-brown shells of wild-type stock. In high-grade specimens the shell approaches a true, near-opaque black with minimal brown undertone. Colour consistency across the colony improves with selective culling over successive generations, and the darkest individuals should be prioritised for breeding to maintain the line. Shell colour intensity varies between individuals and is influenced by calcium availability and water quality. Dark body tissue complements the black shell and distinguishes the Black Ramshorn from simply dark-shelled wild-type individuals. The foot and body are deeply pigmented, producing a cohesive all-black appearance rather than a black shell on a pale or mottled body. This full-body dark colouration is the result of the same melanistic selection that drives the shell colour. Effective on both light and dark substrates, unlike most dark-coloured invertebrates that only show well on pale backgrounds. The near-black shell reads with strong contrast against white sand and pale gravel, while also integrating naturally into dark-substrate planted tanks. This flexibility makes the Black Ramshorn one of the most versatile snail colour forms for mixed substrate setups. Flat coiled shell profile is characteristic of the Ramshorn genus and visually distinct from the conical shells of trumpet snails or the rounded shells of Nerites and Mystery Snails. The flat spiral reads as graphic and clean from above, and the shell's smooth surface shows the black colouration without interruption by ridging or texture.

Self-Regulating if Fed Correctly

Population scales directly with food availability and is the single most important fact to understand before keeping any Ramshorn. In a tank where feeding is conservative and uneaten food is removed regularly, Black Ramshorn numbers remain low and stable. In a tank with consistent excess food the population expands to consume it. Reducing feeding and removing uneaten food after two hours brings numbers back down within weeks as juveniles fail to find adequate nutrition. No traps, chemicals, or manual removal campaigns are needed in a correctly fed tank. Hermaphroditic and capable of reproducing without a mate, which is why population management through feeding is the only reliable long-term control method. Egg clutches are laid as small clear gel masses on hardscape, glass, and plant surfaces. Juveniles emerge fully formed and begin grazing immediately. In a well-fed tank the population can expand quickly; in a conservatively fed tank it self-limits just as reliably. Continuous grazer across all tank surfaces including glass panels, driftwood, plant leaves, hardscape, and substrate. Black Ramshorns move constantly and cover the full tank surface area over the course of a day, consuming algae films, biofilm, decaying plant material, and uneaten food. They do not consume healthy living plant tissue. GH 6+ required for shell integrity. In soft water below GH 6 the shell develops pitting, thinning, and pale patches as the snail draws calcium from its own shell. Maintain GH 6+ consistently and supplement with cuttlebone if your water is on the softer end of the acceptable range. Standard Neocaridina water parameters are fully adequate for Black Ramshorn shell health.
Keeper's Note

A small background population of Black Ramshorns in a shrimp tank is actively beneficial. They process uneaten shrimp food before it degrades water quality, graze biofilm from surfaces the shrimp ignore, and the black shell is visually interesting against both pale and dark substrates in a way that brown wild-type Ramshorns are not. Keep feeding conservative, remove uneaten food reliably, and a colony of 5 to 15 Black Ramshorns in a standard nano shrimp tank manages itself without any intervention.

Policies & Disclaimers

What to expect from your snails, how our guarantee works, and what to do when your order arrives.

Size & appearance

Snail size varies by species and individual. Refer to the listing and selected option for any stated purchase size. Adult or maximum sizes in care information describe growth potential, not a guaranteed size on arrival. Photos represent the species or color variety rather than the exact animals you will receive.

Shells, colors & markings

Shell shape, color, pattern and body coloration vary between individuals and with age. Lighting and aquarium conditions can affect how colors appear. Follow the mineral and water requirements in the species listing to support shell health. Photograph any concerning shell damage on arrival and report it promptly under the Live Arrival Guarantee.

Inactivity after shipping

Snails may remain withdrawn or inactive after shipping and can take several days to settle. Lack of movement alone does not confirm that a snail has died. Do not force a snail out of its shell. If you are concerned about its condition, photograph the unopened packaging and email us within two hours of the carrier’s recorded delivery time. Report the concern promptly even if the snail may simply be inactive; waiting several days does not extend the claim window.

Reproduction & eggs

Reproductive behavior differs by species. Some snails can reproduce readily in freshwater; others have different requirements for successful reproduction. Egg laying is not the same as successful hatching. Read the species listing before purchase rather than assuming all snails will, or will not, reproduce in your aquarium. We do not sex snails. No particular sex, male-to-female ratio or breeding pair is guaranteed.

Feeding & compatibility

Snails have different diets and habitat requirements. Do not assume every species eats algae or can live on algae alone. Assassin snails prey on other snails and are not suitable companions for a collection of ornamental snails. Use the care and compatibility information for the specific species, and check that tankmates will not injure or eat it.

Recognizing activity without forcing a response

A snail may stay retracted after shipping or become active when you are not watching. Some species have a shell door, called an operculum, while others do not; a closed shell or an unfamiliar resting position is not enough by itself to identify a loss.

Do not pull on the body, pry a shell door open or repeatedly handle a snail to make it move. If its condition concerns you, document the unopened bag and contact us within the two-hour window. The possibility of delayed activity does not change the policy’s deadline or turn an unconfirmed loss into an approved claim.

Shell appearance & damage documentation

Shell patterns, growth lines, surface texture and body colors vary with species and age. A photograph of one individual cannot show every pattern you might receive. Natural variation and a concern about physical damage are different questions.

Photograph cracks, chips, erosion or other areas that worry you, together with a wider view and the shipping label. Do not scrape, polish or alter the shell to improve the photo. Report concerning arrival damage promptly rather than assuming it must be accepted or automatically qualifies for a particular resolution.

For ongoing shell health, follow the species’ water and mineral requirements. Measure your water before adding supplements, and avoid treating all snail species as having identical needs.

Eggs, young & population expectations

We do not sex snails, and packs are not assembled to a male-to-female ratio. Snail reproductive biology varies: some species have separate sexes, while others have both reproductive functions. Do not interpret an unsexed pack as a promise that breeding cannot occur.

Ramshorn and bladder snail populations can grow in freshwater, particularly when food is plentiful. Nerites may leave eggs on hard surfaces even though successful development has different requirements from the adults’ freshwater habitat. Check the individual species rather than assuming every egg will hatch or that every snail reproduces in the same way.

A group is not a guaranteed breeding colony. The number and appearance of offspring, or the absence of eggs, cannot be predicted from representative product photos.

Feeding, predators & acclimation

Match the diet to the species. Grazing snails still need an adequate food supply, and an apparently clean aquarium may not provide enough natural grazing. Predatory species such as assassin snails have different feeding and compatibility needs from algae grazers.

Keep ornamental snails away from animals likely to bite their exposed bodies or damage their shells. Follow the specific species’ habitat and acclimation guidance, and check that any treatment used in the aquarium is appropriate for snails.

Quarantine or separate observation can help you inspect new arrivals and their behavior before adding them to an established aquarium. It is care guidance, not an extra claim requirement; follow the arrival documentation rules before transferring animals.

Bonus animals & your paid count

When inventory allows, our policy provides one bonus animal for every five ordered of the same species. Bonuses are discretionary and are not separately covered for refund or replacement. They count toward the total arriving alive when assessing whether your paid quantity was fulfilled.

For example, if you order 10 snails and receive 12, receiving 11 alive fulfills the paid count. If fewer than 10 arrive alive, the shortfall is assessed under the guarantee. Expected bonuses that were not included are not a paid-item shortage.

Checking quantities & reporting a short count

Check the actual animals received against your paid order quantity. For a suspected short count, the full policy calls for a clear counting photo showing all animals, the empty bag and the shipping label before they are introduced into an aquarium. Follow its counting instructions and contact us if you cannot document the count clearly.

Verified miscount claims are resolved with a refund for the missing paid animals under the current policy. A count made after release can be unreliable when animals hide among plants or hardscape.

Before opening: photographs & your first report

Use the email address on the original order and include all arrival concerns in the initial message to support@superiorshrimpaquatics.com within two hours of the carrier’s recorded delivery time. Photograph the sealed bag, visible and countable animals, shipping label, box and packing materials.

If the bag is leaking or damaged, photograph the leak or damage and wet packing before opening. Keep the original photographs and packaging. For cloudy water that prevents counting, take the original cloudy-water photo first and follow the full policy’s specific additional clear-container documentation instructions.

The guarantee contains restrictions on opening bags, acclimation and transfers. Review those instructions before taking action so the evidence needed to assess the claim is preserved.

Read the full guarantee for photo requirements, cloudy-water documentation and claim eligibility before opening or transferring animals. Approved claims are resolved under the options and conditions stated there.

Shipping & coverage limits

Ground shipping carries increased risk for live animals, and the policy reserves the right to refuse guarantee claims on ground shipments. Choose your shipping method carefully.

The guarantee applies to the first delivery attempt. Redirection, pickup holds and carrier delays can affect eligibility under the full policy. Any product-specific coverage restrictions stated in a listing also apply.

Hitchhikers & quarantine

Live aquatic products can carry tiny hitchhikers or eggs despite inspection. Pest-free arrival is not guaranteed. We recommend quarantining new arrivals before introducing them into an established aquarium.

Returns

Care guidance in this tab does not create additional guarantee requirements or exclusions. Please read the full policies for complete eligibility, documentation, resolution and return requirements.
