The Horse Conch is a large, voracious predator. Paul Humann

Overview

The horse conch is one of the largest snails known. Juveniles have a bright orange or brilliant red body; shells are often black, occasionally red or orange. Adults have a plain tan to pinkish shell, which may have a black or brownish proteinaceous layer on the outside. The aperture is almost triangular; the narrow apex of the triangle forms an extensive spout. Adult soft parts are tan, reddish, or brown. A plate of horny material plugs the aperture when the animal is withdrawn.

Feeding

Predators on live food; will eat almost anything.

Aquarium Compatibility

Voracious predators not suitable for reef aquariums, but good for a “species” tank. They will attack and eat almost any smaller mobile animal, particularly smaller snails and clams.


Notes

They are hardy animals tolerant of temperature and salinity swings. If well fed, they grow rapidly. An adult would wreak havoc in a reef tank, but juveniles may arrive uninvited on live rock.
