Description

Spikey Thorn Antler Snail (Clithon diadema)

Overview:
The Spikey Thorn Antler Snail is a striking freshwater snail known for its unique shell covered in small horn-like spikes resembling antlers. With attractive striped or patterned shells and excellent algae-eating ability, this species is both decorative and highly beneficial for maintaining a clean aquarium.

Origin:
Native to Southeast Asia, Clithon diadema is commonly found in coastal streams, rivers, and brackish estuaries.

Feeding:
Primarily herbivorous. Feeds on algae, biofilm, and micro-organisms growing on glass, rocks, plants, and décor. Supplement with algae wafers or blanched vegetables such as zucchini or spinach if natural algae is limited.

Tank / Setup Requirements:

  • Minimum tank size: 20 litres (5 gallons)

  • Provide rocks, driftwood, and plants for grazing surfaces

  • Stable water parameters recommended

  • A secure lid is beneficial as snails may occasionally explore above the waterline

Tank Mates:
Ideal for peaceful community aquariums. Compatible with most small fish, shrimp, and other invertebrates. Avoid snail-eating fish such as puffers or large loaches.

Behaviour:
Peaceful and active algae grazer. Constantly moves across surfaces feeding on algae and biofilm. Like other nerite-type snails, they rarely reproduce in freshwater aquariums.

Experience Level:
Beginner friendly. Hardy and easy to care for, making them excellent additions to planted and aquascaped aquariums.

Water Parameters:

  • Temperature: 22–28°C (72–82°F)

  • pH: 6.5–8.0

  • Water Type: Freshwater

  • Hardness: Moderate to hard water recommended for shell health.
