Common name: Pink Murex

General information

The West Mexican Cerith, scientifically known as Hexaplex erythrostomus, is a species of predatory sea snail belonging to the family Muricidae, commonly referred to as murex snails or rock snails. This species is recognized for its distinctive, robust shell with a pointed spire and variable coloration, often featuring shades of brown with a reddish aperture.

Care

In the aquarium, West Mexican Ceriths are valued for their scavenging abilities. They are adept at cleaning the substrate and rockwork by consuming detritus, uneaten food, and algae. These snails prefer a well-established aquarium with plenty of live rock and a sandy substrate that allows them to burrow and forage. They are relatively hardy and can adapt to a range of water conditions, but stable water quality and parameters are essential for their well-being.

Reproduction

Reproduction in Hexaplex erythrostomus involves the laying of egg capsules on hard surfaces. In the aquarium, successful breeding is rare, but hobbyists may occasionally observe egg capsules attached to the aquarium glass or decorations.

Habitat

The natural habitat of the West Mexican Cerith includes rocky shores and sandy bottoms in the Eastern Pacific, particularly along the west coast of Mexico. They are often found in intertidal zones to subtidal areas where they can scavenge for food and hide from predators.
