General Description
The Assassin Snail Group, scientifically known as Clea helena, is a moderate freshwater invertebrate species characterized by its striking appearance and effective snail population control abilities. They feature a bright yellow shell with chocolate brown stripes, making them visually appealing additions to planted aquariums. These snails are peaceful toward fish and shrimps but are efficient in reducing nuisance snail explosions.
Aquarium Setup
The Assassin Snail thrives in freshwater aquariums with a minimum tank size of 120 liters, ideal for accommodating their active behavior. Maintaining water conditions with a pH range of 6.5-7.5, a temperature between 20.0-23.3°C, and a carbonate hardness (KH) of 2-15 enhances their well-being. It is recommended to refer to the specific requirements for optimal care (see table).
Behaviour
Assassin Snails are opportunistic carnivores that feed on live prey and detritus, primarily targeting smaller snails that cross their path. They tend to remain partially buried in the sediment, emerging to hunt down snails of a similar size or smaller. Despite their carnivorous nature, they exhibit a peaceful temperament in community tank settings, posing no threat to other tank inhabitants.
Feeding and Diet
Being omnivorous, Assassin Snails consume a varied diet consisting of live prey and scavenged detritus. Their diet mainly includes smaller snails, making them an effective solution for controlling snail populations in aquariums. For existing snail infestations, it is suggested to introduce multiple Assassin Snails (ideally 5 per every 15 gallons) to mitigate the issue.
Reproduction & Dimorphism
The reproduction process and dimorphic features of Assassin Snails are notable aspects of their life cycle. Due to their hermaphroditic nature, Assassin Snails can reproduce independently without the need for a mate. Their reproductive capabilities can lead to an effective population control mechanism within the aquarium environment.
Habitat and Distribution
In the wild, Assassin Snails inhabit clean, fast-flowing streams with sandy or muddy substrates. They exhibit adaptability to a wide range of water conditions, including ponds and ditches, showcasing their hardy nature. This adaptability allows them to thrive in various aquatic habitats, making them suitable for home aquariums with diverse setups.
