Compiled by Aquairi from published sources · Published · Updated
Overview
Bumblebee Nerite Snail (Neritina juttingi) is a freshwater (or brackish) snail of the family Neritidae, listed in the Aquairi knowledge base as a beginner-level species. Black-and-yellow striped Nerite resembling a bumblebee. Same care as other Nerites — algae grazer requiring hard alkaline water.
Taxonomy
- Family: Neritidae
- Genus: Neritina
- Scientific name: Neritina juttingi
- Common synonyms: Bumblebee Nerite
Habitat
Neritid snails inhabit tropical and subtropical coastal streams and estuaries worldwide, from East Africa and the Indo-Pacific to the Caribbean. Most species require brackish or marine water for larval development, although adults thrive in pure freshwater aquariums. The Aquairi knowledge base records this entry from: Indo-Pacific.
Tank requirements
- Minimum tank volume: 20 L (5.3 US gal)
- Adult size: 1-2 cm
- Temperature: 22-28 °C (72-82 °F)
- pH: 7-8.5
- GH: 6-18 °dGH
- KH: 4-12 °dKH
- Lifespan: 1-2 years
Diet
A herbivorous grazer. Diet consists almost entirely of biofilm and soft algae rasped from solid surfaces. In the aquarium no supplementary feeding is needed in a mature tank; in nutrient-poor systems, occasional blanched spinach, zucchini or algae wafers supplement intake.
Compatibility
Peaceful algae-grazing snail that does not damage live plants and ignores tank mates of any size. Suitable tank mates listed in the Aquairi knowledge base: Most peaceful fish, Shrimp. Should be kept away from: Loaches, Pufferfish, Crayfish.
Breeding
Sexual reproduction with an obligatory salt or brackish larval phase. Females release planktonic larvae that develop only in higher-salinity water and metamorphose into the juvenile stage there before migrating back upstream. As a result, the species essentially does not reproduce in pure freshwater aquariums; eggs may be laid on hardscape, but the larvae cannot complete development.
Why the Bumblebee Nerite Snail Won't Breed in Freshwater (Neritina juttingi)
Overview
The bumblebee nerite, Neritina juttingi, is a small Neritidae snail from the Indo-Pacific, marked with black-and-yellow striping. Its care matches other nerites: it grazes algae and needs hard, alkaline water. It also shares the amphidromous nerite life cycle that requires brackish or salt water for larval development, so it does not reproduce in a freshwater aquarium.
Sexing
Bumblebee nerites have separate sexes and are not hermaphroditic, so a single snail cannot multiply on its own. The sexes are not reliably distinguishable by eye, which is why a small group is kept to ensure both are present.
Conditioning
Adults stay healthy and lay egg capsules when given hard, alkaline water, plenty of algae and adequate minerals. As with all nerites, conditioning does not enable reproduction, because the larvae still require brackish or marine salinity to develop.
Breeding Setup
To complete the cycle, the larval stage must take place in brackish or saltwater. Keepers either acclimate adults to brackish water or move egg-bearing surfaces into a brackish or saltwater rearing tank, since the veliger larvae need that salinity and specific gravity to become juveniles.
Why It Won't Breed in Freshwater
In freshwater the female deposits hard, white egg capsules on surfaces, each holding many eggs, but no viable snails emerge. The larvae cannot develop without brackish or marine water, so the population does not grow in a freshwater tank despite the eggs being laid.
Common Challenges
The hard white egg capsules cling to surfaces and are difficult to remove, and many keepers find them unsightly. Even with a brackish rearing tank, feeding the tiny larvae is extremely difficult, so captive breeding rarely succeeds.
