Olive nerite snails (commonly referred to by their scientific name Neritina reclivata) are small, attractive freshwater snails often kept in aquariums for their algae-cleaning abilities.

🔍 Basic Description:

• Shell Color & Pattern: Typically olive green or brown, sometimes with dark zigzags, stripes, or spotted patterns. The patterns can vary widely, making each snail unique.

• Size: Usually about ½ to 1 inch (1.3 to 2.5 cm) in diameter.

• Lifespan: Around 1 to 2 years in captivity, sometimes longer with good care.

• Shell Shape: Smooth, rounded shell with a flat operculum (the “door” they close behind them).

🧠 Behavior & Traits:

• Non-aggressive: Peaceful and safe to keep with other aquatic creatures.

• Algae Eaters: Excellent at cleaning tank surfaces, decorations, and plant leaves.

• Escape Artists: Like many nerites, they may climb out of the tank if there’s no lid.

• No Overbreeding Risk: They need brackish (slightly salty) water to reproduce, so they won’t multiply uncontrollably in freshwater.

🌿 Habitat:

• Native Range: Southeastern United States, especially coastal and brackish areas.

• Preferred Conditions:

  • Temperature: 72–78°F (22–26°C)

  • pH: 7.0–8.5

  • Hard water helps maintain shell health.

✅ Tank Role & Benefits:

• Keeps glass and surfaces clean.

• Adds visual interest due to its patterns and slow, graceful movement.

• Doesn’t harm live plants.
