Astrea Snail
Astrea Snail (Astrea tecta)
🐚 Algae-Eating Workhorse – Reef-Safe and Reliable
The Astrea Snail is a reef tank essential—small, hardy, and built for battle against nuisance algae. With a rugged, pyramid-shaped shell and a nonstop appetite, this snail is ideal for keeping glass, rock, and substrate clean without disturbing corals or inverts.
💡 Appearance: Cone-shaped shell with earthy tones and subtle patterning
🌿 Diet: Eats film algae, diatoms, and some hair algae
📏 Size: ~1"
💧 Tank Size: Suitable for nano to large reef aquariums
📈 Reef Safe: 100% reef safe and peaceful
🌀 Behavior: Active grazer, often found on glass or rocks
🔧 Bonus: Helps establish biofilm balance in new or mature systems
🧠 Pro Tip: While they’re great climbers, Astreas may need a gentle flip if they fall on their back—they’re not the best self-righting snails!
🔁 Recommended Qty: 1 snail per 5–10 gallons for effective algae control
