How to Build a DIY Quarantine Tank

All you need for quarantine is a simple container that allows you to view the condition of the fish, is easy to clean on a frequent basis if needed, and doesn't take much effort to set up and teardown. My current hospital tank consists of:

• Clear Rubbermaid or Sterilite plastic tub with a lid
• Filter
• Polyfil stuffing (cheap, disposable filter media)
• Heater (the adjustable temperature allows you to raise or lower the heat to best treat the illness)
• Thermometer
• Water dechlorinator
• Siphon (only use this one for the quarantine system)
• Fake plant décor (for fish to hide in)

For the clear plastic tub, I marked up the side with the number of gallons to help with accurate medication dosing. I also drilled holes in the lid for air and electrical cords to pass through.

The minimal equipment for a quarantine tank includes a heater, thermometer, décor for fish to hide in, and heater if needed.

After watching Aquarium Co-op's quarantine video, I have started using their recommended fish medication trio. It's totally up to you whether you want to prophylactically medicate your fish. Lots of people like to wait and see or use gentler methods like aquarium salt or Indian almond leaves.

Final Tips on Quarantining Fish

I quarantine my fish for four to six weeks, which seems like forever but I've faced fatal fish diseases before and it's just not worth it. Besides you can still enjoy them in their temporary home in the meanwhile. Just keep a close watch on them for any signs of illness.

Also, I like to keep my quarantine setup right next to the kitchen sink so that it's super convenient to do frequent water changes and provide the new fish with lots of clean water.

Finally, feed your fish a good variety of frozen and prepared foods (or even live foods) to boost their immune systems, fatten their bellies, and make their colors truly shine. Best of luck with your new fish and keep on swimming!
