About

Rabbit snails come from the ancient lakes of Sulawesi, Indonesia, and they're unlike anything else you'd typically find in a freshwater tank. That elongated, pointed shell sets them apart immediately, sometimes reaching 8cm, and their wrinkled, expressive faces genuinely do resemble a rabbit's, especially in the yellow and orange color forms. Chocolate, white-spotted, and gold morphs exist too, and each one has real visual character. They move with a deliberate, slow confidence that people either find mesmerizing or frustrating depending on what they expected.

Water parameters matter a lot with these. They originate from mineral-rich, warm lake environments, so they need temperatures in the upper 20s, a pH on the alkaline side, and solid GH and KH readings. Soft or acidic water will pit and erode the shell over months, even if the snail seems fine at first. Many people keep them in Sulawesi-style biotopes alongside other lake species, but they can work in community tanks as long as the parameters align.

Diet is mostly biofilm, algae, and soft organic matter they find while plodding across the substrate and glass. Blanched vegetables, algae wafers, and spirulina-based foods are all accepted. They won't touch most plants, though they may occasionally graze on very soft leaves if they're hungry. Fine substrate suits them better than coarse gravel since they like to dig slightly and push through the surface layer.

They reproduce extremely slowly, dropping a single live snail at a time, so there's no population concern. Browse real tank builds featuring rabbit snails to see how well they anchor a Sulawesi or warm community setup.

These snails pair well with most peaceful community fish that share their parameter requirements. Dwarf cichlids like shell-dwellers from Lake Tanganyika can work if the tank is large enough, and small schooling fish that prefer warmer alkaline water are fine. Other Sulawesi snails and shrimp can coexist without issue. Avoid anything that eats snails, including large cichlids, pufferfish, loaches, and crayfish. Assassin snails are a real threat and should never be kept together. Fish with a habit of pulling or nipping at soft tissue, like certain botias, can stress or injure the snail's exposed foot and face.

Care Notes

The most common mistake is keeping them in standard community tank water that's too cool, too soft, or too acidic. Shell erosion is slow and irreversible, and by the time it's obvious something's wrong the snail may already be declining. Invest in a good GH/KH test kit and supplement if your tap water is soft. They also need warmth consistently above 26C, so pairing them with coolwater species is a dead end. Feed them regularly even if you can't see visible algae growth, because they can slowly starve in an overly clean tank.

Behavior & Aggression

Rabbit snails are entirely non-aggressive. They don't compete with tankmates, don't bother fish or other invertebrates, and show no territorial behavior toward other snails including their own kind. Multiple rabbit snails coexist without any conflict at all. The only behavioral issue you might observe is one snail slowly nudging another out of a feeding spot, which isn't really aggression so much as gravitational determination. They're about as inoffensive as a living creature can get.

Things to Know

  • Requires warm water above 26C, will decline quickly in cooler tanks.
  • Sulawesi origin means standard tap water often needs mineral supplementation.
  • Reproduces very slowly, one live baby at a time, no population explosion risk.
  • Shell degrades in soft or acidic water, always maintain high GH and KH.
