Fish don't pack themselves into boxes, and a full aquarium is far too heavy and fragile to load onto the van with everything else. If you're moving house and taking your tank with you, a bit of planning in the days before move day will keep your fish calm, your water healthy, and your tank in one piece.
Why Your Aquarium Needs Its Own Plan
Water is heavy, and fish are fragile. A 100 litre tank holds around 100kg of water alone, long before you add the glass, gravel and stand. Try to lift that onto a van and you risk a cracked tank, a soaked carpet, or a badly injured back. Fish also feel stress from sudden changes in temperature and water chemistry, so a rushed move can do more harm than a slow, careful one. Treat your aquarium as a separate job from the rest of the house, and start preparing it a few days before everything else gets boxed up. If you'd rather not risk it in your own car, plenty of London movers book a separate man and van service just for the tank, since a small van and one driver can cross town far quicker than working the aquarium around a full house load. For a large or awkward centrepiece tank, our piano and specialist items service is set up to handle exactly this kind of fragile, heavy load.
Start Preparing Three Days Before You Move
Fish do better with advance notice. Stop feeding your fish 24 to 48 hours before the move. This cuts down on waste in the water and means less ammonia building up while they're in transit. Around two to three days before moving day, change roughly 25% of the tank water. Fresh, clean water gives your fish a healthier start and makes the water easier to transport. Get your travel containers ready early too: large lidded buckets, sealable fish bags, and a battery-powered air pump if you're going further than a few miles. Check your new home's plug sockets and think about where the tank will actually sit before you arrive, so you're not hunting for space with a bucket of fish in your hand.
Packing the Decor and Equipment
Never wash your substrate before a move. Gravel and substrate carry the good bacteria that keep your water clear and your fish healthy, so rinsing it away sets your tank back to square one. Scoop it into a bucket with some of the old tank water instead, and keep it damp. Wrap ornaments, rocks and plants in a few layers of bubble wrap, and slide live plants into a sealed bag with a splash of tank water so they don't dry out. Take the filter out last and keep the media sitting in a tub of tank water rather than letting it dry, since dry filter media loses the bacteria that do the hard work of keeping ammonia down. Heaters, pumps and lids should travel separately, wrapped and labelled, so nothing gets lost in the shuffle of a house move. If you're already booking our packing and unpacking service for the rest of the house, ask the crew to leave your fish tank boxes to one side so you can handle them yourself.
Moving the Fish Themselves
Never move fish inside the tank. For a short trip across London, net each fish into a sealed bag filled one-third with tank water and two-thirds with air, then place the bags in a sturdy box so they don't roll around in the car. For a longer journey, a five-litre bucket with a lid and a battery air pump keeps oxygen levels up for longer. Keep the bags or buckets out of direct sunlight and away from extreme heat or cold. A car boot on a warm afternoon can heat up fast, so plan your route and timing with that in mind. Try to keep the total time out of water as short as you can, and get the tank itself moved and refilled first so the fish aren't waiting around in a bag any longer than necessary.
Getting the Tank There in One Piece
Empty tanks travel far better than full ones. Drain the tank completely before it goes anywhere, keeping a few buckets of the old water aside to use again later. Wrap the glass corners and edges in blankets or bubble wrap, and tape the lid shut so it doesn't slide during the journey. Larger tanks, anything over around 60cm, are genuinely a two-person job to lift safely, so don't be afraid to ask for help. If your move already involves a full house removal, our house removals team can factor the tank and its stand into the load plan and make sure it travels upright and secure rather than getting wedged in with everything else. Cabinet stands often need dismantling to fit through doorways, and that's worth sorting out before move day rather than on it.
Setting Up Again in Your New Home
Speed matters once you arrive. Get the tank into position, level and stable, as soon as you can, then refill it using the old water you saved topped up with fresh, dechlorinated tap water. Reconnect the heater and filter before you add a single fish, and give the water 15 to 20 minutes to settle to the right temperature. Float sealed fish bags in the tank for a similar length of time so the temperature equalises gently, then release the fish rather than tipping the bag water in with them. Test your water parameters over the following days, since even a careful move can unsettle the nitrogen cycle for a short while. If your new home isn't quite ready and the tank needs to sit for a few days first, our secure storage service can hold the rest of your belongings while you get the aquarium settled.
Fish Tank Moving Questions
How long can fish stay in a bag during a move?
Fish can usually manage two to three hours in a well-sealed, oxygenated bag or bucket without trouble. Beyond that, water quality and oxygen levels start to drop, so keep the trip as short and direct as you can and get them into their refilled tank as soon as possible.
Do I need to drain the whole tank or can I just take some water out?
For anything above a small nano tank, drain it fully. Even a few centimetres of water left in a large glass tank adds real weight and puts pressure on the seals when it's lifted or tilted, which is often when tanks crack.
Will my fish be okay after such a big change?
Most healthy fish cope well with a considered move. Keeping some of the old tank water, avoiding a full substrate rinse, and reintroducing fish slowly all help reduce the shock. Keep an eye on their behaviour and water readings for the first week.
Can a removals company help move a fish tank?
Yes. Our crews handle fragile, heavy and awkward items every week, from pianos to aquariums, and can plan the tank into your move alongside the rest of your furniture. Get in touch before moving day so we can talk through the size, weight and access at both ends.
Moving a fish tank takes patience, but a little preparation goes a long way for you and your fish. Get every other part of the move sorted properly, and the aquarium becomes just one more job done well rather than a last-minute panic. Ready to book the rest of your move?
