Just be mindful of their growth potential and take precautions to avoid an overabundance of snails in your tank.

Peaceful Red Ramshorn Snail Tank Mates

Red Ramshorn snails are peaceful little creatures that add to community tanks. However, it’s essential to choose tankmates that won’t harm them. Here are some great options:


  • Corydoras catfish: These peaceful bottom-dwellers are excellent scavengers and won’t bother your snails.

  • Rasboras: These small, colorful fish are active and peaceful, making them good tank mates for red ram horn snails. 
  • Danios: These active fish are another excellent choice for peaceful mates. Choose a smaller variety, as some larger danios can nip at snails. 
  • Gourami: Peaceful gouramis like honey gouramis and dwarf gouramis are good choices for tank mates with red ramshorn snails.

  • Predatory fish: Avoid any fish known to eat snails, such as puffers and loaches.
  • Scavenger fish: Avoid fish that compete with snails for food, such as Plecostomus catfish.

You can create a peaceful and harmonious environment for your red ramshorn snails by choosing suitable tank mates.

How They Fare With Living Plants

Ramshorn snails are one of the many snail species that can be kept as pets in aquariums. Like other snails, ramshorns can be good for controlling algae and maintaining a healthy tank environment.

However, one concern with ramshorn snails is their tendency to eat living plants. Some aquarists choose to avoid snails altogether to protect their vegetation. Despite this, some owners enjoy having ramshorn snails in their tanks and appreciate watching them ride around on the surfaces.

Sometimes, ramshorn snails can coexist peacefully with other tank inhabitants, such as red cherry shrimp and apple snails. Additionally, varieties like the blue ramshorn snail and pink ramshorn snail can add unique colors to the aquarium, making them attractive additions. 

Tank Setup & Caring for Ramshorn Snails

Ramshorn snails are relatively easy to care for and can thrive in various tank setups.

Here’s a guide on setting up a tank and caring for Ramshorn snails:

Ramshorn Snail Tank Size & Setup:

  • Tank size: Ramshorn snails can do well in tanks of various sizes, from small nano tanks to larger aquariums. A 5-gallon tank can comfortably house a small group of snails, while larger tanks accommodate more. 
  • Water parameters: Ramshorn snails are adaptable to a wide range of water conditions, but they prefer water temperatures between 68-82°F (20-28°C), pH levels between 7.0-8.0, and moderate hardness. Ensure stable water tank parameters by performing regular water changes (20-30% every two weeks) and using a good quality aquarium filter.
  • Substrate: While not mandatory, a substrate like sand or gravel can provide a natural environment for your snails to burrow and explore. Avoid sharp-edged substrates that could damage their delicate shells.
  • Plants: Live plants benefit Ramshorn snails by providing hiding places, grazing surfaces and helping maintain good water quality. Choose plants that are easy to care for and suitable for your tank size and parameters. Some good options include Java moss, Hornwort, and Anacharis. 
  • Decorations: Smooth rocks, driftwood, and other aquarium decorations can enrich your snails and create a more visually appealing tank. Ensure decorations are clean and free of sharp edges.

Caring for Ramshorn Snails:

  • Feeding: Ramshorn snails are scavengers and readily eat algae, biofilm, residue, and leftover fish food. You can supplement your diet with blanched vegetables like cucumber, zucchini, or spinach. Avoid overfeeding, as this can lead to water quality issues.
  • Breeding: Ramshorn snails are prolific breeders and can quickly multiply if conditions are favorable. If you don’t want a snail explosion, control their population by limiting food availability, removing unwanted snails, or keeping them with snail-eating fish like loaches or puffers (be sure the fish are compatible with your other tank inhabitants).
  • Maintenance: Regularly perform water changes, clean the filter, and siphon the substrate to remove waste and maintain good water quality. Monitor your tank parameters and adjust them as needed.

Additional Tips:

  • Ramshorn snails can escape from open tanks, so use a tight-fitting lid.
  • Avoid using copper-based medications, as copper is toxic to snails.
  • If you have other fish in your tank, ensure they are compatible with Ramshorn snails. Some fish may eat or harass the snails.

Following these guidelines, you can create a thriving environment for your Ramshorn snails and enjoy their presence in your aquarium.

Ramshorn Snails Role as Aquarium Pest

Ramshorn snails can be good freshwater aquarium inhabitants as they help clean the tank by eating decaying plants, uneaten fish food, and soft green algae.

However, they can quickly become a pest if their population is uncontrolled. Ramshorn snails are highly prolific breeders; their eggs can be hidden in plants or decorations bought from pet stores. Once introduced into an aquarium, they can quickly multiply and overrun the tank.

They also have a reputation for ramshorn snails eating the leaves of aquarium plants, which can be frustrating for aquarists who take pride in their planted tanks. Ramshorn snails can also inadvertently harm aquarium fish by consuming fish eggs and nibbling on the fins of slow-moving fish.

One way to control ramshorn snail populations is to introduce predators like the gold inca snail or blue velvet shrimp. These animals will feed on the young ramshorn snail population and help keep their numbers in check.

Manually removing dead ramshorn snails or any eggs found in the tank can also help prevent a population explosion. It’s important to note that ramshorn snails have a lifespan of around 1-2 years, so if left unchecked, the population will eventually decline as the snails reach the end of their life cycle.

Ramshorn snails are also known as pets and can be a good tank addition for many aquarists. These snails typically have a small body or foot size, but as they grow older, their size can increase. Ramshorn snails prefer to spend their time at the bottom of the tank, moving around slowly. They are non-aggressive towards other tank mates, making them a popular choice for community tanks. A healthy ramshorn will consume green lettuce leaves and other plant matter, but they may turn to baiting snails or even dead fish if they are hungry. It is essential to watch the ramshorn snails in your tank, as they can reproduce quickly and overcrowd the environment.

In terms of ramshorn snail size, they can vary depending on its age and environment. The snails become larger as they mature, with baby ramshorn snails starting much smaller. Ramshorn snails also come in different varieties, such as Sulawesi snails, which may have different body sizes than regular ramshorn snails. Despite ramshorn snails size ramshorn snails are generally peaceful creatures that can add a unique touch to your aquarium setup. Just provide them a balanced diet and monitor their population to ensure a healthy tank environment.
