Military Helmet Nerite at a glance
Adult size: 1 inch · Minimum tank/pond: 5 gallons · Difficulty: beginner · Diet: algae grazer · Lifespan: 1-2 years.
Military Helmet Nerite (Neritina pulligera) is a freshwater invertebrate kept by aquarists for planted-tank cleanup crew + breeding-line collecting. Hardy and forgiving of typical beginner mistakes when given proper water chemistry.
Where Military Helmet Nerite comes from
Military Helmet Nerite (Neritina pulligera) is native to freshwater habitats across multiple continents. The captive-bred Military Helmet Nerite sold at most LFS comes from generations of farmed stock and is generally hardier and better-acclimated to tank conditions than wild-caught equivalents. Wild specimens are occasionally available for keepers chasing original-bloodline coloration or biotope-accurate stocking.
Military Helmet Nerite tank size and setup
Military Helmet Nerite requires a minimum of 5 gallons for healthy adults. The minimum is based on the species' adult size (1 inch), territorial range, and behavior pattern. Most Military Helmet Nerite sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.
For a Military Helmet Nerite setup: mature planted tank or low-stocked community tank with stable parameters, mineralized substrate (or remineralized RO/DI for Caridina), low-flow filtration that does not suck up shrimplets, and minimal copper exposure (avoid copper-treated medications).
Military Helmet Nerite prefers freshwater parameters: Temperature: 70-78°F pH: 6.5-7.5 GH: 4-12 dGH KH: 3-8 dKH Ammonia + nitrite: Both 0 ppm Nitrate: Under 20 ppm long-term Copper: 0 (especially critical for invertebrates)
Use dechlorinator on every water change. Test parameters weekly during cycling, biweekly once stable. Stable consistency beats sliding-scale "ideal" parameters.
What Military Helmet Nerite eats
Military Helmet Nerite is a algae grazer. Provides natural algae control by grazing on filamentous, hair, and turf algae throughout the tank. Supplemental nori sheets and algae wafers ensure adequate nutrition when tank algae is depleted. Avoid copper-based algaecides - they kill Military Helmet Nerite. Feed Military Helmet Nerite appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Military Helmet Nerite tankmates and compatibility
Military Helmet Nerite works alongside peaceful community fish. Avoid mixing with fin-nippers (some tetras, barbs), aggressive cichlids, or large predators. Best in shrimp-only or mostly-shrimp tanks for breeding success - any larger fish will eat shrimplets.

Military Helmet Nerite adult size and lifespan
Military Helmet Nerite reaches 1 inch at adulthood with a captive lifespan of 1-2 years with proper care. Females carry eggs under the abdomen until hatch; in stable tanks, breeding populations sustain themselves indefinitely.
Can you breed Military Helmet Nerite?
Yes - Military Helmet Nerite is one of the more readily-bred freshwater invertebrates. Most freshwater snails self-fertilize and reproduce continuously in stable tanks; some (nerites) require brackish water for egg viability.
Common Military Helmet Nerite diseases and problems
Military Helmet Nerite is susceptible to standard freshwater diseases (ich, columnaris, fin rot, bacterial infections). Quarantine new Military Helmet Nerite for 4 weeks before adding to your display tank. Treat fish in a separate hospital tank to avoid affecting plants and inverts. Most disease outbreaks trace back to poor water quality, chronic stress, or skipped quarantine.
