Description
Fitzroy River Snail – Notopala alisoni
The Fitzroy River Snail (Notopala alisoni) is a freshwater mollusc native to the Fitzroy River system in Queensland, Australia. This species is highly regarded for its robust shell, ecological role as a grazer, and adaptability to aquaria that replicate its natural habitat. Its presence enhances biodiversity and contributes to algae control in freshwater systems, making it both an interesting and functional addition to riverine or community tanks.
Features of Fitzroy River Snail – Notopala alisoni
• Robust, conical shell with earthy brown to tan tones
• Adult size ranges from 4–6 cm in length
• Slow-moving, peaceful species that grazes on algae and detritus
• Hardy and adaptable to a range of freshwater conditions
• Plays an important ecological role in nutrient cycling
• Can live several years under optimal conditions
The Best Aquarium Size for Fitzroy River Snail – Notopala alisoni
A minimum aquarium of 40 litres is suitable for a small group, although larger tanks of 80 litres or more are recommended to provide ample grazing area and stable water quality. A length of at least 60 cm ensures enough space for movement and territorial grazing.
Tank Mate Compatibility for Fitzroy River Snail – Notopala alisoni
This species is peaceful and can coexist with other non-predatory freshwater inhabitants. Ideal tank mates include:
-
Small freshwater shrimps such as Amano Shrimp
-
Peaceful dwarf rainbowfish
-
Pygmy Corydoras
-
Otocinclus Catfish
-
Other non-aggressive snail species
Diet for Fitzroy River Snail – Notopala alisoni
Fitzroy River Snails are primarily herbivorous grazers. Their diet includes algae, biofilm, and decaying plant matter. In captivity, supplementation with blanched vegetables such as zucchini, spinach, or cucumber promotes growth and shell health. Providing calcium-rich foods or cuttlebone enhances shell strength and longevity.
Aquarium Setup Fitzroy River Snail – Notopala alisoni
Aquarium Filtration
A gentle sponge or canister filter ensures clean water without harming the snail. Maintain stable water parameters with low nitrate and phosphate levels for optimal health.
Aquarium Plants
Include robust aquatic plants such as Vallisneria, Anubias, or Java Fern. The snail can graze on biofilm and detritus on leaves while leaving plants largely unharmed.
Aquarium Lighting
Moderate lighting supports plant growth and natural algae development for grazing. A photoperiod of 8–10 hours daily is recommended.
Aquarium Heating
Maintain temperatures between 22–26°C. Avoid rapid fluctuations, which can stress the snail and affect feeding behaviour.
Aquarium Substrate
Fine sand or smooth gravel replicates natural riverbeds and allows snails to forage effectively. A calcium-rich substrate promotes shell strength.
Aquarium Decorations
Provide rocks, driftwood, and leaf litter to create natural grazing surfaces and hiding spaces. Smooth surfaces prevent shell damage and encourage natural exploratory behaviour.
