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)
