Description
Sun Thorn Snail (Neritina sp.)
Overview:
The Sun Thorn Snail is a striking freshwater snail recognized for its rounded shell adorned with short, sunburst-like thorn patterns. Its unique appearance and excellent algae-eating abilities make it both decorative and highly beneficial for planted and community aquariums.
Origin:
Native to Southeast Asia, Neritina species are commonly found in rivers, streams, and estuarine environments with clean, flowing water.
Feeding:
Primarily herbivorous. Feeds on algae, biofilm, and micro-organisms growing on aquarium surfaces such as glass, rocks, plants, and décor. If natural algae is scarce, supplement with algae wafers or blanched vegetables like zucchini or spinach.
Tank / Setup Requirements:
-
Minimum tank size: 20 litres (5 gallons)
-
Provide rocks, driftwood, and plants for grazing surfaces
-
Stable water parameters recommended
-
Secure lid advised, as nerite snails may occasionally climb above the waterline
Tank Mates:
Suitable for peaceful community aquariums with small fish, shrimp, and other invertebrates. Avoid snail-eating species such as puffers or large loaches.
Behaviour:
Peaceful and active algae grazer. Constantly moves across surfaces feeding on algae and biofilm. Like other nerite snails, they may lay eggs in freshwater, but the eggs will not hatch without brackish water conditions.
Experience Level:
Beginner friendly. Hardy and easy to care for, making them ideal for planted aquariums and aquascapes.
