What Do Ramshorn Snails Eat in Aquariums?

Ramshorn snails in aquariums are aquatic snails that are known to eat a variety of foods. They may feed on soft algae, small snails, and dead fish in the tank. Ramshorn snails can also consume soft green algae and act as a natural source of food control for algae growth.

Additionally, they may lay eggs on aquarium glass or other surfaces, developing new snails in the tank. Ramshorn snails are often overlooked as pets but can be good choices for a freshwater aquarium.

Caring for them involves monitoring water parameters and ensuring enough snail food is available. If you have ramshorn snails in your tank, avoid snails or shrimp that may prey on them, such as assassin snails.

Another popular snail species for aquariums are the red ramshorn snails or Planorbarius corneus. These snails may also be found in pet stores and can be good tank cleaners. Ramshorn snails have a lifespan ranging from a few months to a few years, depending on their environment. 

They come in various colors, such as blue Ramshorn, red cherry shrimp, and gold Inca snail. It’s crucial to control ramshorn snail population in the tank to prevent them from overpopulating and causing issues.

Ramshorn Snail Tank Requirements

Ramshorn snails are relatively low-maintenance freshwater snails that are popular additions to aquariums. They are known for their ability to help keep tanks clean by eating algae and detritus. Here are some of the basic requirements for keeping ramshorns in your tank:

  • Tank size: Ramshorns can thrive in various tank sizes, from small 5-gallon tanks to larger community tanks. However, it is essential to avoid overcrowding, which can lead to water quality problems. A good rule of thumb is to start with 1-2 snails per 10 gallons of water.
  • Water parameters: Ramshorns prefer neutral to slightly hard water with a pH of 7.0-8.0 and a temperature of 68-82°F. They are relatively tolerant of a wide range of water parameters, but avoiding sudden changes in water chemistry is essential.
  • Filtration: While not strictly necessary, a filter can help keep the water quality stable and oxygenate the snails. A sponge filter is a good option for small tanks, as it is gentle on the snails and provides good biological filtration.
  • Substrate: Ramshorns do well with various substrates, including sand, gravel, and bare-bottom tanks. However, they prefer softer substrates, such as sand, as it is easier for them to burrow in.
  • Plants: Live plants are not essential for ramshorns but can provide hiding places and additional food sources. The snails will eat algae and residue off the plants and any dead or decaying plant matter.
  • Food: Ramshorn snails are scavengers and will eat various things, including algae, detritus, biofilm, and even blanched vegetables. If you have a heavily planted tank, they should be able to find enough food on their own. However, you can supplement their diet with sinking fish food or algae wafers.
  • Breeding: Ramshorn snails are prolific breeders and can quickly overrun a tank if not controlled. If you do not want them to breed, you can keep only male snails, as females can store sperm for multiple matings. You can also remove any egg clutches that you see.
  • Compatibility: Ramshorn snails are generally peaceful and will not bother other fish or invertebrates. However, they should not be kept with fish known to eat snails, such as loaches or puffers.

With proper care, snails can be a valuable addition to your aquarium. They are hardy, easy to care for and help keep your tank clean.

Ramshorn Snail Care and Reproduction

Ramshorn snails are known for their unique appearance, with some species, like the blue ramshorn snail and pink ramshorn snail, being particularly striking. These freshwater aquatic snails can make for exciting pets in an aquarium, but caring for them is essential.

Caring for ramshorn snails involves providing them with a healthy environment and ensuring they have enough food. Ram horn snails may also eat live plants, so it’s essential to make sure the snail is well-fed.

Ramshorn snails can be good tank cleaners, as they will eat dead plants and other debris in the aquarium. Promptly removing dead snails is essential, as they can cause the water quality to deteriorate and may even cause other ramshorn snails to die.

Reproduction is another exciting aspect of ramshorn snail care. These snails will lay their eggs on surfaces like plants or decorations in the tank.

The eggs will hatch into young ramshorn snails and develop into adult snails. The older the snail, the larger it will grow. Ramshorn snails spend most of their time at the bottom of the tank, although they may sometimes climb plants or decorations.

They are also known to be quite hungry, so feed them regularly. Ramshorns can be kept with other peaceful aquarium fish and shrimp but may eat trumpet snails or snail mystery snails. Make sure to keep a close eye on any group of snails to prevent overpopulation.

The Lifespan of Ramshorn Snails

The average lifespan of a Ramshorn Snail is around one year in captivity with proper care. However, some individuals can live longer, up to three years, under ideal conditions.

Several factors can affect the lifespan of a Ramshorn Snail, including:

  • Water Conditions: Ensure the water in their tank is clean and free of harmful chemicals. Regular water changes are essential.
  • Diet: Provide them with a balanced diet of algae, biofilm, and blanched vegetables.
  • Temperature: Maintain the water temperature within their preferred range, which is typically between 68°F and 82°F (20°C and 28°C).
  • Predators: Avoid keeping them with fish that are known to eat snails.
  • Stress: Minimize stress by providing them with hiding places and avoiding sudden environmental changes.

If you provide your Snails with reasonable care, they can thrive and live long healthy lives.

Finding Ramshorn Snails in the wild

Finding Ramshorn Snails in the wild can be a fun and rewarding experience, especially if you enjoy aquatic life. These snails look unique with spiral-shaped shells and can easily be found in various bodies of water, such as ponds and lakes.

When searching for ramshorn snails, watch for the black and red varieties, known as planorbella duryi and planorbarius corneus.

These snails are quite hardy and adapt well to different environments. In the wild, you may also come across dead ramshorn snails, but finding a healthy ramshorn snail can be truly satisfying.

Rams horn snails tend to be prolific breeders, so don’t be surprised if you stumble upon many snails in a single location. It’s important to note that while collecting snails in the wild can be exciting, it’s still a good idea to research how to care for them properly if you plan on keeping ramshorn snails as pets.

These snails will also thrive in tanks with live plants, as they feed on soft green algae growing on the leaves. Additionally, in aquariums, snails will also eat dead fish, and live plants are never completely safe from their appetites.
