Snails
Tank-bred freshwater snails, raised in the USA and fed calcium supplements so they arrive with strong, unpitted shells.
Mystery snails are peaceful with fish, shrimp, and each other, and they work through leftover food and algae without touching healthy plants. One of the easiest additions you can make to a freshwater tank.
Snails ship in oxygenated water in insulated packaging — never dry in an envelope. In cool weather they may be sluggish on arrival; bring them up to temperature slowly and they perk right up.
