Overview:

The Red Onion Snail, scientifically known as Vittina semiconica, is a small and attractive freshwater snail native to Southeast Asia. With its vibrant red and brown coloration, it is a popular choice for aquarium enthusiasts. Proper care is essential to ensure the well-being and longevity of these fascinating creatures.

Habitat:

1. Tank Size: A tank of at least 5 gallons is suitable for a small group of Red Onion Snails.
2. Substrate: Provide a soft substrate like sand or smooth gravel to prevent damage to their delicate foot.
3. Water Conditions:
   • Temperature: Maintain a water temperature between 72-78°F (22-26°C).
   • pH Levels: Keep the pH level around 7.0-8.0.
   • Water Hardness: Soft to moderately hard water is preferred.
4. Filtration: Use a gentle filtration system to maintain water quality without creating strong currents that may disturb the snails.

Feeding:

1. Diet: Red Onion Snails are detritivores, primarily feeding on decaying plant matter, algae, and leftover food.
2. Supplements: Offer a variety of sinking pellets, algae wafers, and blanched vegetables like spinach or zucchini. Calcium supplements, such as cuttlebone, can support shell development.

Social Behavior:

1. Compatibility: Red Onion Snails are peaceful and can coexist with most aquarium fish and invertebrates.
2. Grouping: They are social creatures and thrive in groups. Keeping at least three snails is recommended.

Health and Maintenance:

1. Shell Health: Monitor the condition of their shells; any abnormalities may indicate a calcium deficiency. Provide a calcium source if needed.
2. Water Changes: Perform regular water changes (around 10-20% weekly) to maintain optimal water quality.
3. Handling: Minimize handling as much as possible, and when necessary, handle them gently to avoid causing stress or damage to their delicate bodies.

Breeding:

1. Reproduction: Red Onion Snails are known to lay eggs on hard surfaces. If conditions are favorable, they may breed in the aquarium.
2. Separation: If you wish to control population growth, separate and raise the juvenile snails in a separate container.

Caution:

• Chemicals: Avoid the use of copper-based medications, as they can be harmful to snails.

By providing a suitable environment and proper care, you can enjoy the unique beauty of Red Onion Snails in your aquarium. Regular observation and attention to their needs will contribute to their well-being and longevity.
