Avoid

Major changes immediately before leaving

Difficulty

Beginner

Stabilise the system before departure

Complete routine maintenance early enough to observe the tank afterwards. Do not replace all filter media, add new livestock, start medication or rebuild plumbing the night before leaving. A boring, stable aquarium is the goal.

Pre-portion food

Most healthy adult fish tolerate a brief reduction in feeding better than a tank tolerates generous guesswork from a sitter. Label portions by tank and day. Remove the main food container so extra feeding is not easy. Fry and specialised animals need a more detailed plan.

Check equipment and backups

• Confirm filters restart after a power interruption.
• Check heaters, air pumps, lids and water levels.
• Provide battery air or generator instructions where outages are a real risk.
• Move power boards away from drip paths.
• Leave spare airline, a net and dechlorinator in one marked place.

Write an emergency sheet

1. List normal conditions.Include expected temperature, water level and equipment sounds.
2. Define red flags.Dead fish, no filter flow, overheating, leaks or gasping.
3. Give one action per problem.Keep instructions simple and safe.
4. Add contacts.Include you, a backup keeper and relevant trades or veterinary help.

Common mistakes

• Doing a massive clean immediately before departure.
• Using untested automatic feeders.
• Leaving vague feeding instructions.
• Expecting a non-aquarist to diagnose disease.
• Providing no plan for power failure or leaks.
