Travel and safety for your fish

Vet visits, holidays, moving house: sooner or later your fish will travel. The right carrier, proper car restraint, journey prep: our guides cover the gear and habits that turn a trip into a non-event.

The key point : Moving an aquarium takes planning: transport bags, keeping filter bacteria warm and wet, and a methodical restart.

Our dedicated guides

• Aquarium electrical safety: GFCI protection and good habits

  Heater, filter, lighting near the water: what electrical precautions keep an aquarium safe for fish and people?

• Drip acclimation: settling new fish in safely

  How to acclimate new fish with the drip method: equipment, drip rate, duration and special cases for a smooth, stress-free transfer into the tank.

• Transporting Fish Long Distance: Plane, Car and Stress

  How do you transport fish long distance without stressing them? Double-bagging, thermal insulation and water quality management on the road.

• Jumping Fish: Which Species Are Likely to Leap Out of the Tank

  Danios, killifish, bettas... some fish species jump out of the water easily. Why a well-fitted lid is essential and what warning signs to watch for.

• Fish nets and handling: the stress-free method

  Choosing the right aquarium net and handling fish without stress: size, soft mesh, the two-net technique and alternatives to netting.

• Heater or filter failure: the emergency kit that saves the aquarium

  Aquarium heater or filter failure: the right moves hour by hour and the 50-80 € emergency kit that prevents a wipe-out (battery air pump, thermometer).

• Away for Months (Study Abroad, Expat Move): How to Arrange Aquarium Care?

  An automatic feeder covers a two-week holiday, not several months away. Realistic options for not sacrificing your fish's welfare: a trusted person, temporary rehoming, or rehoming for good.

• Aquarium and children: safety, rules and good habits at home

  An aquarium with children at home: a stable cabinet, a closed hood, secured sockets and clear rules. The complete safety guide, age by age.

• Extended power cut: how to save your aquarium?

  Power cut and aquarium: fish hold out 2 to 6 hours without risk, then you must oxygenate and insulate. The life-saving steps, hour by hour.

• Bringing your fish home from the pet store: transport and acclimatisation done right

  Bringing fish home from the pet store properly: a short, warm journey, the bag kept dark, then 30 to 45 minutes of drip acclimatisation. The complete method.

• Moving House With an Aquarium: How to Transport the Filter and Heater Without Crashing the Cycle

  Draining the filter or letting it dry out during the trip kills off much of its nitrifying bacteria. How to keep the filter media wet and alive while moving house.

• Regulated or Protected Aquarium Fish: What to Check Before You Buy

  Asian arowana, seahorses... a handful of aquarium fish species are protected under CITES with specific rules. How to check before you buy.

• Cold Shock in Transport: Winter's Underestimated Risk

  A transport bag that cools quickly in a car or in the cold outdoors exposes a fish to cold shock. How to prevent it in winter.

• Do Fish Feel Pain? What the Science Says

  Long doubted, a fish's ability to feel pain now rests on solid evidence that justifies handling them gently.

• Alarm Substance: Why You Should Isolate an Injured Fish After Handling

  An injured fish releases a chemical signal that stresses the whole shoal. A study explains why isolating it helps healing and calms the tank.

• Should a Fish Be Sedated for Transport? What a Betta Study Shows

  A betta study shows a low dose of clove oil reduces stress during prolonged transport.

• Home Renovation and Paint: How to Protect Your Aquarium From Toxic Fumes

  Paint, glue, spray insecticide: these fumes can kill fish from a distance. Here's how to protect your tank during home renovation work.

• A Pinch of Salt in the Transport Water: Why It Reduces Fish Stress

  Adding non-iodized salt to the transport bag or bucket limits stress-related electrolyte loss, according to a study on farmed fish transport.

• Buying Aquarium Fish by Mail Order: What to Check Before You Order

  Ordering fish online for postal delivery exposes them to a much longer transport stress than a simple trip from the local pet store.

• Why transport stresses fish: what cortisol reveals

  Handling, a sealed bag, temperature swings: transport triggers a measurable hormonal cascade in fish. Understanding this mechanism explains why some transport precautions matter more than others.

• Fasting a fish before transport: useful or pointless?

  Withholding food the day before a move is a long-standing practice in live fish transport. What it actually changes for water quality inside the bag.

• How many fish in one transport bag? What loading density research says

  Cramming several fish into a single bag to save time is tempting. A study on transporting rainbow trout in plastic bags puts a precise figure on the loading density not to exceed.

• The pH drops in the transport bag: should you worry?

  A water test after a sealed-bag trip often shows a pH much lower than at departure. Research on fishkeeping transport explains why that drop isn't automatically bad news.

• Aquarium and cats: how to protect your tank from curious felines

  A curious cat sees an aquarium as a game: a solid lid, a stable stand and distractions elsewhere are usually enough to protect fish and equipment.

• Heatwave and aquariums: how to cool the water without thermal shock

  During a heatwave, aquarium water can top 30°C: a fan, pausing lighting and a bottle of ice cool the tank without a sudden, harmful thermal shock.

• Long-distance transport: encapsulated microalgae against ammonia in the bag

  Over a simulated 15-day transport, an Amazonian microalgae capsule limits ammonia and raises female guppy survival to 97.8%, against 6.7% with no treatment. A reason to rethink additives for long trips.

• What actually happens between the wholesaler and the pet store, according to a field study

  A study tracked water quality and fish behaviour through an entire commercial transport chain. Stress doesn't follow the same pattern across species, which changes how a new fish should be brought home.

• Fish transport: mere handling makes parasites worse

  A study on guppies shows that mechanical disturbance of the transport bag alone, with no change in water or temperature, is enough to worsen a parasite infestation.

• New fish hugging the bottom: when it stops being acclimation

  The bottom-dwelling reflex is documented in zebrafish, and it is measured in minutes. After a few days the explanation lies elsewhere — often in the water.

• Fish transport: why the risk isn't the same depending on trip length

  A scientific review finds two opposite risks depending on transport duration: a pH drop on a short trip, rising ammonia on a long one. The precautions that matter aren't the same either way.

• Noise and vibration in the car: a stressor that also hits the fish's hearing

  A car ride does not only expose fish to motion and temperature: a study on an otophysan fish shows noise alone raises cortisol and shifts the hearing threshold.

• Shipping fish in cold weather: does an insulated box with a heat pack really hold temperature?

  A study measured, with sensors, the real temperature inside a fish shipping box sent through cold weather. Here is what the numbers show about how well the insulation actually works.

• Koi herpesvirus: water temperature decides the outcome, not the purchase date

  A 2003 study varied water temperature after experimental infection. Between 13 and 23 °C, the very same virus goes from zero mortality to 95%.

• Wild Yellow Tang: why some divers puncture its swim bladder

  A scientific study compared several ascent methods for Yellow Tang caught off Hawaii. The technique that looks the most shocking turned out to be the safest in the short term.

• Fish treatment and quarantine: what a survey of 350 hobbyists and retailers reveals

  A UK survey compared the real-world practices of hobbyists and retailers facing freshwater fish disease. The results question whether individual precautions alone are enough.

• How long can a fish stay in a transport bag?

  A well-prepared transport bag keeps a fish safe for several hours, but past a certain point, oxygen levels and temperature become critical.

• Eugenol or MS-222 for anesthetising a fish several times over? What a study found

  A study compared eugenol and MS-222, buffered or not, on zebrafish anesthetised repeatedly, looking at recovery and behaviour after each episode.

• Transporting Your Fish and Moving an Aquarium Without Breakage or Stress

  Bags, cool box, food-grade containers, order of operations: the complete method for transporting your fish and moving an aquarium safely, step by step.
