The Florida Fighting Conch makes a great addition to larger tanks. They eat brown diatoms (algae) that grow on live sand beds. Fighting Conchs will bury themselves in the sand bed and clean the upper layers. These Jumbo Conchs should not be placed in an aquarium less than 100 gallons.Conchs belong to a Class known as Gastropods, which make up the largest class of Mollusks. Conchs grow by increasing their swirling body while producing a protective shell. This shell protects their soft body from predators. They use a pad, or foot, that extends from their shell which allows them to drag their shell along. As they drag their shell often times their mouth and eyes can be seen coming out from the opening of the shell.
