Description:

Shell:

• • oval, tapered, matte 
• • short apex, often corroded
• • dark variable striped patterns
• • light to dark brown basic color
• • aperture and septum: grey, shiny
• • size:.  - 25 mm ,height 23 mm

         Operculum:

• greyish white to yellow with a red line on the rim
• Body:
• black and white pattern
• grey sole

Range, habitat:

• tropical climate, 22 - 32 °C
• Sumatra, Indonesia, Polynesia, Malaysia, Thailand
• Brackish water channels
• Freshwater river estuaries

Development and reproduction:

• • dioecious, but no outward differences
• • the female attaches whiteish, hard, oval cocoons to hard substrates
• • hatched Vehliger larvae wander from fresh to brackish water to marine waters. On the journey back they develop into snails.
• • Thus, reproduction in the aquarium can practically be ruled out.
• • The editor does not have data about the life span of these snails. Individual specimens have been kept in tanks for four years and longer.

         Food:

• tirelessly grazes on hard substrates (hard green algae)   
• digs in the muck and eats there    
• seems to take powdered food, ingredients do not matter
• fruit, vegetables, raw pasta

Socialization in the Aquarium:

It is not very vulnerable to attacks and can thus be kept together with various fish species. Dwarf shrimp and other gastropods with the exception of Anentome helena are unproblematic. They should be kept in small groups as they like company. Unobtrusive worker, only leaves the water when about to starve or when massively bothered in the tank. The tanks should have algae when this snail is put in, as these wild-caught gastropods do not eat artificial food at first. However, Neritina coromandeliana will take additional food offered to it pretty soon.
