Blue Ramshorn Snail are a shoaling species — they need 6+ to feel safe and show their full colour. Larger shoals stay calmer, eat better, and look stunning.

Maintain these water conditions for optimal health and vibrant colors
Blue Ramshorn Snail (Planorbella duryi) is a small, peaceful freshwater snail for planted aquariums, shrimp tanks and calm community displays. This blue colour form gives the familiar flat ramshorn shell a cool translucent tone, so it works both as a useful grazing animal and as a visible bit of movement on wood, leaves and glass.
This listing is for live aquarium-bred snails, not outdoor pond stock. They are best kept in mature aquariums with stable water quality, gentle filtration and enough minerals for shell growth. They browse soft algae, biofilm, decaying plant material and leftover foods, but they should not be treated as a cure for poor maintenance. The cleanest results come when they are added to an already balanced tank and fed lightly.
Blue Ramshorns are popular because they are active, visible and genuinely useful in the right tank. They spend the day grazing over glass, hardscape and plant leaves, cleaning up film algae and small leftovers before those leftovers break down. In planted aquariums they usually leave healthy plants alone, though they will pick at dying leaves and soft decaying growth. That makes them a good partner for aquascapes where you want a natural cleanup crew without adding aggressive livestock.
The species behind most aquarium ramshorns is widely recognised as Planorbella duryi. USGS records the Seminole rams-horn as a Florida species, while aquarium-trade sources note that captive lines are bred in colour forms including blue, red and brown. In customer terms, the important point is simple: this is a small ramshorn-type aquarium snail, selected for colour and tank suitability, not a wild UK pond snail to release outdoors.
A mature aquarium of 20 litres or more is a sensible starting point for a small group. They can live in nano tanks, but stability matters more than volume alone. Use a cycled filter, avoid ammonia or nitrite, and keep the aquarium covered enough that snails cannot wander out. Sponge filters and low-flow internal filters are ideal because they keep water steady without throwing the snails around.
Shell quality is the main husbandry detail. Ramshorn shells need calcium and carbonate hardness. If the water is very soft or acidic, new shell growth can become thin, pale or pitted. In soft-water areas, add a snail-safe mineral source such as cuttlebone, crushed coral in a media bag or a dedicated invertebrate mineral supplement. Avoid copper medications and check plant fertilisers before use, because copper can harm snails and shrimp.
In a mature community aquarium, Blue Ramshorns usually find plenty to graze: soft algae, biofilm, decaying plant edges and tiny food particles. They also appreciate occasional blanched courgette, spinach, algae wafers or invertebrate foods. Feed sparingly. Overfeeding is the fastest way to turn a useful snail group into a population problem, because ramshorns reproduce readily when there is constant surplus food.
They are not a replacement for water changes or gravel cleaning. Think of them as a finishing crew: they tidy small organic films and leftovers, while you still control feeding, maintenance and stocking.
Blue Ramshorn Snails are peaceful with shrimp, small tetras, rasboras, livebearers, Corydoras, Otocinclus and most gentle community fish. Avoid known snail predators and pickers such as pufferfish, Botia-type loaches, assassin snails, crayfish and large rough cichlids. Some curious fish may nip soft antennae, so watch new combinations for the first few days.
If you are building a mixed invertebrate tank, they pair naturally with Amano Shrimp. If you want to compare ramshorn options, see our Pink Ramshorn Snail and Planorbella duryi Ramshorn Snail listings.
Ramshorn snails lay clear jelly-like egg clutches on glass, leaves and hardscape. Warm water and heavy feeding speed up development, so numbers can increase quickly in tanks with lots of spare food. This is not usually a problem when feeding is controlled. Remove excess food, prune dying plant matter and avoid leaving sinking pellets overnight if you want the group to stay modest.
These are live animals and they can be quiet after shipping. Float the bag to equalise temperature, then acclimate slowly with small amounts of aquarium water before release. Place them on a hard surface or plant leaf rather than dropping them into deep substrate. It can take a little while for ramshorns to open and start moving, especially after courier transit.
