The shell base colour ranges from dark olive and brown to warmer gold tones, overlaid with black markings and banding that vary in pattern between every individual. No two King Koopa Nerites look exactly alike -- the number, size, and arrangement of the horn protrusions, combined with the unique black marking pattern on each snail, makes every specimen genuinely individual. They are less commonly available than Zebra or Olive Nerites, and their unusual appearance makes them one of the most conversation-worthy invertebrates in the freshwater hobby. Algae-grazing performance is consistent with other Nerite species -- continuous, broad-spectrum, and highly effective. Cannot breed in freshwater. Fully safe with all shrimp. Shell requires GH 6+ and a pH above 7.0 for best long-term shell health.\u003c\/p\u003e\n\n    \u003cspan class=\"section-label\"\u003eAppearance\u003c\/span\u003e\n    \u003ch2\u003eHorns, Shell \u0026amp; Colour\u003c\/h2\u003e\n    \u003cdiv class=\"bullet-list\"\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eRounded horn-like protrusions across the shell surface -- the defining feature of the species\u003c\/strong\u003e -- the horns of the King Koopa Nerite are rounded and blunt-tipped rather than the sharp, spine-like projections of the Sun Thorn Nerite. They are distributed irregularly across the shell surface in varying numbers and sizes, giving each snail its characteristic sea-mine silhouette. The horns are a natural structural feature of the shell and are prone to occasional minor breakage during normal activity, which does not harm the snail. The rounded horn profile gives the King Koopa a more armoured, prehistoric appearance than the sharper-spiked thorn Nerites.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eDark olive-to-gold base with variable black markings -- unique pattern on every individual\u003c\/strong\u003e -- the shell base colour ranges from dark olive-green and brown in some individuals to warmer golden-tan tones in others. Across this base runs a pattern of black markings, banding, and blotching that is entirely unique to each snail -- no two King Koopa Nerites share the same distribution of black against the base colour. This individual variation makes each snail a genuinely one-of-a-kind specimen, and a group of three to five in the same tank will display noticeably different patterning from one to the next.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eUp to 1 inch at maturity -- larger and more visible than many Nerite species\u003c\/strong\u003e -- King Koopa Nerites reach approximately ¾ to 1 inch in shell diameter at maturity, making them clearly visible at normal tank-viewing distance. The combination of size, horn structure, and individual patterning gives them a presence in the tank that smaller or smoother Nerite species do not achieve.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eUncommon in the hobby -- less frequently available than Zebra, Olive, or Tiger Nerites\u003c\/strong\u003e -- King Koopa Nerites are not as widely bred or distributed as the most common Nerite species and are less reliably available from general aquatic retailers. When available they are among the most sought-after Nerite variants for aquarists who want both effective algae control and a genuinely unusual display invertebrate.\u003c\/span\u003e\n    \u003c\/div\u003e\n\n    \u003cspan class=\"section-label\"\u003eBehaviour \u0026amp; Care\u003c\/span\u003e\n    \u003ch2\u003eGrazing \u0026amp; Husbandry\u003c\/h2\u003e\n    \u003cdiv class=\"bullet-list\"\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eExceptional broad-spectrum algae grazer -- consistent with other Nerite species\u003c\/strong\u003e -- King Koopa Nerites graze continuously across glass, hardscape, driftwood, plant leaves, and substrate, consuming algae films, biofilm, cyanobacteria, and fine organic deposits. They are particularly effective on glass surfaces and smooth hardscape. In a well-established tank with adequate algae and biofilm growth they require no supplemental feeding; in newer or heavily stocked tanks supplement with algae wafers or blanched vegetables.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eCannot breed in freshwater -- population is completely stable\u003c\/strong\u003e -- like all Nerite species, King Koopa Nerites require brackish or marine water for their larvae to develop. Egg capsules -- small, hard, white oval dots -- may be deposited on hardscape, glass, and plant surfaces but will not hatch in freshwater. You will never have more King Koopa Nerites than you introduce.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003ePrefers alkaline water -- pH above 7.0 for best long-term shell health\u003c\/strong\u003e -- King Koopa Nerites are more sensitive to acidic water than some other Nerite species. In water below pH 7.0 the shell is prone to erosion over time, gradually thinning the base shell and degrading the horn structure. Maintain pH above 7.0 and GH 6+ consistently. Standard Neocaridina parameters are ideal. Not recommended for Caridina tanks with low pH and soft water.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eKeep water line low or cover the tank -- Nerites climb readily\u003c\/strong\u003e -- King Koopa Nerites climb above the waterline and will exit the tank through any gap. Keep the water line at least 5–7cm below the rim or use a fitted lid.
