Astrea Snail

Astrea Snail – Efficient Algae Eater for Freshwater and Brackish Aquariums

The Astrea Snail (Delphinatia or Helicina species) is a popular freshwater and brackish aquarium snail known for its impressive algae-eating capabilities. Sporting a sturdy, spiral-shaped shell with distinct ridges and often marked with subtle color patterns, the Astrea Snail is both functional and visually appealing.

This hardy snail actively grazes on various types of algae, including green film algae and diatoms, helping to keep tanks clean and maintain balanced water conditions. Its constant movement over glass, rocks, and plants makes it a reliable natural cleaner without harming healthy plants or tank inhabitants.
