Ramshorn Snails Species Summary

Ramshorn snails are a group of freshwater snails whose shells are flat, disklike coils, similar to a ram’s horn. They belong to the Planorbidae family and breathe air by means of a lunglike organ. They can be found in many aquariums, sometimes unintentionally, as they can hitchhike on plants and decor. The term “ramshorn snail” is used in two different ways. In the aquarium trade, it is used to describe various kinds of freshwater snails whose shells are planispiral, meaning that the shell is a flat coil. Such shells resemble a coil of rope, or (as the name suggests) a ram’s horn.

In a more general natural history context, the term “ramshorn snails” is used more precisely to mean those aquatic pulmonate gastropod mollusks in the family Planorbidae that have planispiral coiled shells. Ramshorn snails have been bred for the aquarium trade and various color forms have been selected. The two species commonly found in aquariums are Planorbella duryi and Planorbarius corneus, both in the family Planorbidae. One species (Columbia ramshorn, Marisa cornuarietis) is from a totally different family, the Ampullariidae. Ramshorn snails can sometimes become a nuisance in an aquarium because some of them breed so profusely.

Ramshorn snails belong to the family Planorbidae, and they are classified under the phylum Mollusca. These gastropods are characterized by their unique spiral-shaped shells, which resemble a ram’s horn, hence their name. The shells come in various colors, including red, brown, and black, adding a striking visual appeal to any aquarium or pond.

These invertebrates are hermaphroditic, meaning each individual possesses both male and female reproductive organs. However, they still require a partner to reproduce. During mating, they exchange sperm, and subsequently, each snail can lay egg masses containing up to 100 eggs. These eggs are enclosed in a transparent gelatinous substance, making them appear like tiny clusters of grapes.

Ramshorn Snails Lifespan

The lifespan of Ramshorn snails can vary based on several factors, including species, environmental conditions, and overall care provided. In general, these snails have relatively short lifespans compared to some other aquarium inhabitants. However, with proper care and attention, their lifespan can be extended to some degree.

Species Variation

Ramshorn snails belong to a diverse family with multiple species, and their lifespans can differ slightly between these species. While some species may typically live for around six months to a year, others might have slightly shorter or longer lifespans. For example, the Giant Ramshorn snail (Marisa cornuarietis) is known to have a longer lifespan compared to some other common Ramshorn snail species.

Environmental Conditions

The environment in which Ramshorn snails are kept plays a crucial role in determining their lifespan. When housed in a well-maintained and balanced aquarium or pond with suitable water parameters, they are more likely to thrive and live longer.

Water quality is especially important for their well-being. Regular water changes, efficient filtration, and proper oxygenation are essential to keep ammonia, nitrite, and nitrate levels in check. Elevated levels of these substances can be harmful to the snails and may shorten their lifespans.

Diet and Nutrition

A nutritious and balanced diet is key to promoting the health and longevity of Ramshorn snails. In their natural habitats, they consume algae, detritus, and decaying plant matter, which provide essential nutrients. In captivity, it is crucial to offer them a varied diet that includes algae-based foods and blanched vegetables, such as spinach, zucchini, or lettuce.

Overfeeding or providing poor-quality food can lead to health issues and may reduce their lifespan. It is important to ensure that any uneaten food is promptly removed from the tank to prevent water contamination.

Population Density

The population density of Ramshorn snails in the aquarium or pond can also influence their lifespan. In an overpopulated environment, competition for resources can become intense, leading to stress and a higher risk of disease transmission. Maintaining an appropriate snail population for the tank size and conditions can help promote their overall health and longevity.

Predators and Stressors

In the wild, Ramshorn snails face natural predators that can significantly impact their survival and lifespan. In captivity, the presence of certain fish or invertebrates can pose a threat to their well-being. For instance, some fish species may consume snails, and certain invertebrates like crayfish could be aggressive towards them.

Moreover, stressful conditions, sudden changes in water parameters, or exposure to harmful chemicals can compromise their immune system and reduce their lifespan.
