Marisa cornuarietis — Giant Rams Horn Snail

The Giant Ramshorn Snail is a large, disc-shaped snail with a boldly coiled shell and a spotted or striped body pattern. Unlike smaller ramshorns, this species is an avid plant consumer and can cause significant damage to aquarium vegetation. Native to Central America, it is best suited for tanks with hardy or no live plants, where it serves as a vigorous algae and detritus cleaner.
