Snails look like the easiest animals to move — no biting, no bolting, no noise — but a mixed collection hides a real problem: species sharing a tank at home may have arrived there from very different waters. Some shrug off a cool car ride; others, like the warm-water rabbit snails from Sulawesi's lakes, are set back by hours of chilling. Moving day succeeds when the packing respects those differences instead of treating every shell the same.
Sort the collection by temperature tolerance
Before any water is poured, list your species in three rough bands: the cold-tolerant, the middling, and the swing-sensitive. Nerites and mystery snails generally sit in the hardier bands; sulawesi rabbit snails, some tylomelania relatives and delicate shrimp-adjacent tankmates belong in the protected band. This sorting decides everything downstream — which tub goes where in the box, which group gets the heat pack's attention, and which tubs you check first on arrival.
Containers that protect shells and water
Use rigid, lidded tubs rather than bags: snail shells chip and crack when bags slosh and knock together, and a rigid wall keeps a stable pocket of water around each animal. Fill tubs with the snails' own tank water, add a piece of plant or a blanched vegetable scrap for grip and grazing, and group by species so a stressed tub never involves the whole collection. Leave an air gap under each lid — mystery snails breathe air and will climb to use it. Label every tub with species and count before it goes into the box.
Holding temperature steady inside one box
Line a foam or insulated box with a towel, set the swing-sensitive tubs in the centre, and pack the hardier tubs around them as living insulation. If the day is cold, add a heat pack wrapped in cloth and taped so it warms the box's air rather than touching any tub — direct contact can cook the nearest snails while the rest stay cold. In hot weather the same structure works in reverse with a cool pack at the edge. Wedge everything so tubs cannot slide, keep the box level in the car, and avoid opening it en route; every look costs warmth.
Settling them at the other end
Set up destination tanks before the box is opened, with water matched as closely as you can to home conditions. Float each closed tub or rest it beside the tank until temperatures equalise, then introduce the snails gently, sensitive species first while your attention is freshest. Expect some to stay shut for hours — retracted and quiet is normal after a move. Offer food once they begin to emerge, and watch the sensitive band over the following days for shells that never open.
A collection with this many individual needs is hard to hold in your head on moving day, which is why the KinsLe Pet Passport keeps each pet's records together in one portable packet — species notes, water preferences and quirks ready at the new home the moment the box opens.
