Freshwater fish quarantine tank checklist
For fishkeepers bringing home new freshwater fish for an established community tank. This covers a bare quarantine setup, not medications or treatment plans.
What to get
10-gallon aquarium or appropriately sized quarantine tank
Secure aquarium lid
Sponge filter seeded from an established aquarium
Air pump
Airline tubing
Check valve
Adjustable aquarium heater if needed
Digital aquarium thermometer
Bare-bottom tank mat
PVC elbow hideouts
Aquarium-safe water conditioner
Freshwater liquid test kit
Small aquarium net reserved for quarantine use
Dedicated aquarium-only bucket
Quarantine observation log
Who this list is for
New freshwater fish should have a separate place to settle before joining an established community tank. This checklist is for fishkeepers setting up a bare quarantine tank with separate tools, not choosing medications or treatment plans.
How to use this list
Start with the 10-gallon aquarium or appropriately sized quarantine tank, bare-bottom tank mat, secure aquarium lid, and PVC elbow hideouts. Set up the sponge filter seeded from an established aquarium with the air pump, airline tubing, and check valve. Add an adjustable aquarium heater if needed, then confirm conditions with the digital aquarium thermometer, water conditioner, and freshwater liquid test kit.
Common mistakes
Do not move the small aquarium net or dedicated aquarium-only bucket back and forth between quarantine and the display tank. A seeded sponge filter is useful, but it does not replace checking water with the liquid test kit. Avoid treating the quarantine tank as a decorated second aquarium; the bare bottom and simple PVC hideouts make observation and cleanup easier.
What is on this list
You will find the tank, lid, seeded sponge filter, air equipment, heater option, thermometer, water conditioner, test kit, net, and bucket. The quarantine observation log gives you one place to record what you see. Cross off anything you already own, but keep quarantine-only equipment clearly separated from community-tank supplies.
Before you add fish
Check the lid, filter, air line, and temperature before the new fish arrive. Keep the observation log beside the tank and reserve the net and bucket for this setup. For health concerns or decisions beyond observation and basic setup, consult an aquatic veterinarian or qualified fish professional.
