The tricolour banding is bolder and more contrasty than the two-tone patterning of standard horned Nerites, and combined with the spine structure the result is one of the most immediately eye-catching small snails available in the freshwater hobby. Like all Nerites they are outstanding algae grazers, particularly effective at keeping glass clear, and they cannot complete their reproductive cycle in freshwater, meaning population is permanently fixed at whatever number you introduce. Small at 0.5 to 0.8 inches, low bioload, and fully safe with all shrimp. Horns break easily during normal activity and handling, which is harmless to the snail.\u003c\/p\u003e\n\n    \n    \u003cspan class=\"section-label\"\u003eAppearance\u003c\/span\u003e\n    \u003ch2\u003eThree Colours and Horns\u003c\/h2\u003e\n    \u003cdiv class=\"bullet-list\"\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eDistinct yellow, black, and orange banding across the shell.\u003c\/strong\u003e The tricolour patterning is the defining characteristic of this variant.

They are brittle and break easily during normal activity, handling, or transit. Broken horns cause no harm to the snail and do not regrow.
