Colombian Giant Ramshorn Snail Aquarium
Giant Ramshorn snail Marisa cornuarietis is a type of freshwater snail that belongs to the family Ampullariidae. These aquatic creatures are known for their gelatinous appearance and can grow up to 50 mm in size.
Marisa cornuarietis, commonly called the Giant Columbian Ramshorn Snail, is an invasive species from Central America. They can be found in various countries, such as Colombia, Venezuela, Costa Rica, and Panama.
These omnivorous snails feed on vegetation, including aquatic plants, and can reproduce quickly, leading to potential ecological problems. They are also known to compete with native snails for resources.
The juvenile snails of the Marisa snail are striped and have a gill that allows them to breathe underwater. As the young snails grow, they develop a calcium-based shell that resembles a ram’s horn, hence their name.
These large snails lay their eggs on hard surfaces above the waterline, and the eggs hatch into small juveniles. The Ramshorn Snail is a nonindigenous species and has been listed in the USGS Nonindigenous Aquatic Species Database.
Note: In environments characterized by lower calcium concentrations and softer water, Ramshorn snails are notably vulnerable to shell deterioration.
Distribution and Natural Habitat of Marisa Cornuarietis Snails
The Marisa Cornuarietis snail, also known as the Giant Ramshorn, has a widespread distribution across two main areas:
Native range:
- Northern South America and Central America, including Bolivia, Brazil, Colombia, Costa Rica, Cuba, French Guiana, Guyana, Panama, Suriname, Trinidad and Tobago, and Venezuela.
- They are believed to be native to the Magdalena and Orinoco river systems in Colombia and Venezuela.
Introduced range:
- Established populations exist outside their native range in several locations, including:
- Caribbean nations: Cuba, Puerto Rico (Cowie and Hayes 2011), Martinique, Guadeloupe, Dominican Republic.
- Southern USA: Florida, Texas, California, and Idaho.
- Africa: Sudan and Tanzania.
- Spain
- Introductions were likely accidental, mainly through the aquarium trade and cargo vessels.
Natural Habitat
The Marisa Cornuarietis snail thrives in freshwater habitats with abundant vegetation. They are typically found in:
- Slow-moving and shallow waters (up to 1 meter deep)
- Lakes, rivers, ponds, irrigation systems, and swamps
- Areas with dense aquatic plants
- They can tolerate slightly brackish water (up to 4 parts per thousand salinity).
These snails play a role in their natural ecosystem as detritivores, consuming decaying organic matter and algae, which helps maintain water quality. However, they can become invasive in areas outside their native range, where they can compete with native species for resources and disrupt the ecological balance.
The Difference Between the Giant Colombian Ramshorn snail and the Giant Ramshorn Snail
The Giant Colombian Ramshorn Snail and the Giant Ramshorns are the same species, scientifically known as Marisa cornuarietis. They are relatively large snails native to northern South America and several Caribbean islands.
There is some confusion surrounding the name because “Giant Ram horn Snail” is a common name for this species. At the same time, “Giant Colombian Ramshorn Snail” is a more specific, descriptive term that highlights its origin. But both names refer to the same snail.
These snails are popular in the aquarium trade due to their:
- Large size: They can grow up to 2 inches (5 cm) in shell diameter, making them impressive additions to freshwater tanks.
- Algae eating habits: They help control algae growth in aquariums.
- Peaceful nature: They are generally friendly towards other tank inhabitants, making them suitable for community tanks.
However, it’s important to note that they can also be:
- Prolific breeders can reproduce quickly, potentially leading to overpopulation in aquariums.
- Destructive to plants: While primarily eating algae, they can consume and damage live plants, especially soft-leaved varieties.
If you’re considering adding Giant Colombian Ramshorn Snails to your aquarium, carefully research their care requirements and choose tank mates that won’t prey on them.
Breeding Giant Ramshorn Snails
Breeding Colombian Giant Ramshorn Snails can be a fascinating hobby for those interested in invertebrates. These relatively giant snails, also known as the great ramshorn, can be found in the continental United States.
A widespread species within the apple snail family, they are not to be confused with the Colombian ramshorn apple snail, which can carry diseases like schistosomiasis.
The giant rams-horn snail is a freshwater snail, Gastropoda, prosobranchia, and is often used in research studies such as the ones conducted by Howells et al. in BMC Evolutionary Biology.
The eggs are laid in large gelatinous masses on aquatic vegetation when breeding. The eggs are visible as small dots but swell up to 4 mm. If you are lucky enough to see the snail laying eggs, you may also know the snail moving around in its natural habitat.
It is essential to monitor the breeding process closely to ensure the health and well-being of these fascinating creatures.
