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.

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.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eDark body tissue complements the black shell\u003c\/strong\u003e 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.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eEffective on both light and dark substrates\u003c\/strong\u003e, 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.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eFlat coiled shell profile is characteristic of the Ramshorn genus\u003c\/strong\u003e and visually distinct from the conical shells of trumpet snails or the rounded shells of Nerites and Mystery Snails.

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.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eHermaphroditic and capable of reproducing without a mate\u003c\/strong\u003e, 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.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eContinuous grazer across all tank surfaces\u003c\/strong\u003e 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 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\n    \u003ca href=\"\/es\/collections\/freshwater-snails-parent\" class=\"cta-block\" title=\"Freshwater snails | algae-eating clean-up crew for your tank – superior shrimp \u0026amp; aquatics\" aria-label=\"Freshwater snails | algae-eating clean-up crew for your tank – superior shrimp \u0026amp; aquatics\"\u003e\u003cspan class=\"cta-icon\"\u003e🐌\u003c\/span\u003e\u003cdiv class=\"cta-text\"\u003e\n\u003cstrong\u003eBrowse more freshwater snails\u003c\/strong\u003e\u003cp\u003eExplore Nerite Snails, Mystery Snails, and more.
