The Clea Helena, also known as Assassin Snail or Malaysian Trumpet Snail, is a fascinating and efficient freshwater snail that adds a touch of practicality and interest to any aquarium. With its unique appearance and remarkable predatory behavior, the Clea Helena is a popular choice among aquarists who seek a natural and effective solution for controlling pest snail populations in their tanks. Originating from Southeast Asia, particularly Malaysia and Indonesia, these snails are known for their peaceful nature, scavenging habits, and their ability to help maintain a balanced aquarium ecosystem. Let's explore a detailed description of these remarkable snails, including essential information on their appearance, water conditions, tank setup, feeding habits, and care.

Appearance:

• Striking Shell: The Clea Helena has a striking conical-shaped shell with distinctive yellow, brown, and black patterns, making it visually interesting in the aquarium.
• Size: They are small to medium-sized snails, reaching an adult length of around 1 to 2 inches (2.5 to 5 centimeters).

Water Conditions:

• Temperature: Maintain a tropical water temperature range of 72°F to 82°F (22°C to 28°C) to ensure the well-being of Clea Helena snails.
• pH Level: Aim for a slightly acidic to neutral pH level between 6.5 and 7.5 to replicate their natural habitat.
• Water Hardness: Provide a moderately soft to moderately hard water with a hardness level between 5 and 15 dGH.

Tank Setup:

• Tank Size: Clea Helena snails can be kept in a small to medium-sized tank, depending on the number of snails and other tank inhabitants.
• Substrate: They prefer a soft substrate to burrow and scavenge for food effectively.
• Hiding Spots: Provide hiding spots with rocks, driftwood, or caves to offer them security and mimic their natural habitat.

Feeding Habit:

• Predator of Pest Snails: Clea Helena snails are efficient predators of pest snails, such as common pond snails and Malaysian trumpet snails, helping to control their populations in the aquarium.
• Scavengers: They also scavenge for leftover food and decaying matter, contributing to the cleanliness of the tank.

Care:

• Peaceful Nature: Clea Helena snails are generally peaceful and can be kept with other peaceful tank mates, including small fish and shrimp.
• No Overfeeding: Avoid overfeeding to prevent an excessive population of Clea Helena snails if their primary food source (pest snails) is limited.
• Observation: Monitor their behavior and appearance to ensure they are healthy and showing no signs of stress or illness.
