Description
The Waterhouse Snail (Notopala waterhousei) is a native Australian freshwater snail known for its distinctive spiral shell and efficient algae-grazing abilities. Found in rivers and floodplain systems, particularly across the Murray-Darling Basin, this species plays an important ecological role in maintaining clean aquatic environments. In aquariums, Waterhouse Snails are valued for their hardiness, peaceful nature, and natural ability to control algae and detritus. As a protected native species, sourcing is done ethically and legally.
Features of Waterhouse Snail (Notopala waterhousei)
• Native to Australia, primarily the Murray-Darling Basin
• Large, thick spiral shell ranging in colour from beige to olive-brown
• Grows up to 6–8 cm in length
• Herbivorous grazer that consumes algae, biofilm, and decaying plant matter
• Extremely hardy and tolerant of a wide range of water conditions
• Peaceful and non-invasive; safe for planted and community aquariums
• Long lifespan of 3–5 years under proper care
The Best Aquarium Size for Waterhouse Snail
A minimum tank size of 40 litres is recommended, though these snails thrive best in larger, mature aquariums with established biofilm. Ensure stable water conditions and sufficient surface area for grazing.
Tank Mate Compatibility for Waterhouse Snail
Waterhouse Snails are peaceful and should be kept with non-aggressive tank mates that won’t attempt to eat or harass them. Suitable companions include:
• Rainbowfish
• Bristlenose Catfish
• Empire Gudgeon
• Native Shrimp (e.g., Macrobrachium species)
• Hardy livebearers like Platies
Diet for Waterhouse Snail
This species feeds primarily on soft algae, biofilm, and detritus. Supplement their diet with:
• Algae wafers or sinking herbivore pellets
• Blanched vegetables such as zucchini, spinach, or cucumber
• Soft aquatic plant trimmings and naturally decaying matter
Avoid overfeeding and ensure food is removed before it deteriorates.
Aquarium Setup for Waterhouse Snail
Aquarium Filtration
Use gentle but efficient filtration to maintain clean water while avoiding strong flow that may disturb the snail. Sponge filters or adjustable canister filters are ideal.
Aquarium Plants
Safe with most aquatic plants. Provide live vegetation to encourage natural grazing and shelter. Hardy species like Vallisneria, Java Fern, and Hornwort are suitable.
Aquarium Lighting
Moderate lighting promotes algae growth for natural feeding. Avoid high-intensity lighting that may stress the snail or lead to excessive algae blooms.
Aquarium Heating
Maintain a stable temperature range between 20–26°C. A heater may be required in cooler climates.
Aquarium Substrate
Fine sand or smooth gravel allows easy movement and natural foraging behaviour. Avoid sharp substrates that may damage the snail’s foot.
Aquarium Decorations
Include driftwood, rocks, and vertical surfaces for algae growth and grazing. Ensure all décor is aquarium-safe and free from copper-based treatments.
