Ramshorn Snails
Species Profile
Ramshorn Snails (Planorbella duryi) are hardy freshwater gastropods characterized by their flat, coiled spiral shells resembling a ram's horn, coming in color morphs ranging from wild brown and leopard spots to vibrant red, pink, and blue. Often unfairly labeled merely as "pest snails," they are actually one of the most efficient, non-stop cleaning crews you can introduce to a planted tank. They cruise across hardscape, glass, and plant foliage to consume brown diatoms, soft algae films, and decaying plant matter before it fouls your water column. Crucially, their rasping mouthparts are not strong enough to chew through healthy plant foliage, so your high-tech stem plants and delicate carpeting runners remain untouched. Because their reproduction rate directly tracks how much uneaten fish food and organic debris lingers in the tank, they act as the ultimate real-time barometer for your system's nutrient balance.
**Note: All livestock orders will come carefully packaged with solid wall Styrofoam insulation and shipped via 1-day shipping only. No extra insulation needs to be added to your cart for your livestock.
Quantity: Each order includes 10 Ramshorn Snails. Shell color and size may vary slightly, as each snail is a unique live animal.
Key Features & Notes
- Distinctive spiral-coiled shell adds organic shapes and color variety across the substrate and hardscape.
- Relentless detritivore that recycles uneaten fish food, diatoms, and dying plant matter before ammonia spikes occur.
- Completely safe with live aquatic plants, feeding strictly on decaying foliage rather than healthy growth.
Acclimation & Care Instructions
- Float the sealed transport bag for 15 to 20 minutes to equalize water temperatures before opening.
- Drip-acclimate over 30 to 45 minutes using airline tubing to adjust them smoothly to your tank's GH, KH, and pH.
- Maintain a stable pH above 7.0 with ample mineral hardness; acidic water will degrade and pit their thin spiral shells.
- Control feeding habits responsibly; excessive leftover fish food and organic waste will trigger rapid population growth.
- Supplement with sinking algae wafers, calcium blocks, or blanched zucchini if kept in super clean display tanks.
- Avoid using copper-based plant treatments, algaecides, or medications in aquariums housing ornamental snails.
- Color morphs and shell patterns vary across specimens; photos represent healthy stock in mature planted setups.

Frequently Asked Questions
1. Will Ramshorn Snails eat healthy aquatic plants or tear up carpeting?
No. Ramshorn Snails lack the radular jaw strength to break down healthy living plant cells. If you see a cluster of them congregating on a leaf, they are consuming dying, rotting, or melting tissue, or grazing micro-algae films off the surface. They do you a favor by trimming dead weight before it decays into the water column.
2. How do I stop Ramshorn Snails from taking over my planted tank?
Their population is directly tied to the tank's food supply. They do not multiply out of nowhere; high populations are a sign of overfeeding, excessive detritus accumulation, or melting plants. Dial back your feeding schedule, vacuum out stubborn detritus, and their population will naturally balance out into a modest, manageable cleanup crew.
3. How do Ramshorn Snails reproduce in an aquarium?
Ramshorn Snails are hermaphroditic, meaning any two mature snails can breed together. They lay small, flat, jelly-like egg clutches on glass, hardscape, and plant leaves that hatch into self-sufficient baby snails within 1 to 3 weeks.
4. What tank mates should I pair with Ramshorn Snails?
They cohabit peacefully with standard planted tank fauna, such as Neocaridina shrimp, Otocinclus, Corydoras, Siamese Algae Eaters, and small schooling tetras. If you want to keep their numbers in check, species like Assassin Snails or small loaches will readily hunt them. Avoid keeping them with dedicated mollusk predators like pea puffers or crayfish unless intended as live food.
