Description

The rabbit snail is a large snail with an elongated shell up to 10 cm, an intense orange or yellow body and a head with two long tentacles reminiscent of a rabbit's ears. It is slow, peaceful and striking, and does not eat healthy plants.

It comes from Sulawesi lakes with warm, alkaline water, and that is its demand: it does not do well in cool or acidic water, and in a temperate community tank it slowly fades away.

It is livebearing and slow: the female releases a single large, fully formed young every so often. It never becomes a pest.

Habitat

It comes from the Malili lakes of Sulawesi, above all Lake Towuti: clear, warm, slightly alkaline water with stone and sand bottoms.

In the aquarium it wants stable, warm, alkaline water, a sandy bottom and some sinking food, because a clean tank does not offer enough for its size.
