[edit] Alternative names

[edit] Synonyms

Clea helena, Anentome Cleo

[edit] Sexing

Difficult to sex.

Not hermaphrodites, so need a male and female counterpart in order to reproduce. Growth rate is slow (a single egg once a month or so) and eggs are laid singly under water and are often eaten by other tank mates. So typically very slow breeders.

[edit] Tank compatibility

This snail will be peaceful towards fish tank mates, as long as they are not predatory. However, this snail will eat any other snails it finds within its environment.

[edit] Diet

This snail relishes other snails for dinner, and will willingly rid your tank of troublesome Ramshorn Snails, Pond Snails and even full size Malaysian Trumpet Snails, they will hunt them down and suck them out of their own shells. When these are not available, it can be supplemented with pellet foods, they will also sift through detritus.

• If you overfeed the tank and there is leftover food left lying around, these snails will prefer that food source to other snails.

[edit] Feeding regime

Supplementary feedings needed only if no snails are present.

[edit] Environment Specifics

This snail thrives in a well maintained mature tank with good water flow and a high GH level. It prefers a sandy substrate to sift through.

[edit] Behaviour

An active predatory snail which hunts other snails.

[edit] Identification

This snail has a chunky conical shell that is ridged and dark brown in colour with several pale cream-yellow bands around it.
