Quick Answer
Mystery snails are larger ornamental freshwater snails with active personalities. They need stable water, calcium, and enough food, and they should not be kept with fish that nip antennae or eat snails.
Care and Setup Notes
- Leave air space above the water because females lay egg clutches above the surface.
- Remove uneaten vegetables before they foul the water.
- Watch shell growth as a simple water-mineral warning sign.
