If you’re wondering, how can you keep a quarantine tank cycled then you’re in the right place.
Here I’m going to answer the same question.
Normally, you don’t need to keep a quarantine tank cycled. However, you can keep your quarantine tank cycled by keeping hardy fish and a filter running in the quarantine tank.
How to keep quarantine tank cycled?
Once your quarantine tank is cycled then you can easily keep the tank cycled by keeping a fish in the tank and a filter running and doing regular tank maintenance.
However, there are some unique things you’ll need to keep in mind while keeping a quarantine tank cycled.
1. Keep the setup simple
Your quarantine tank should contain only the necessary things.
It should only have a filter and a heater.
You should avoid keeping any substrate, decorations, and live aquarium plants in your quarantine tank.
Keeping your quarantine tank set up simple is important because the main purpose of your quarantine tank is to quarantine a new fish and treating a fish before adding it into your display tank.
And adding extra things like substrate and plants requires maintenance. And it can make things complicated while treating your fish.

2. Add hardy fish in the quarantine tank
Once your quarantine tank is cycled then you will need to keep a hardy species of fish in the tank.
Some of my recommendations of hardy species you can keep in your quarantine tank are as follows:
- Play ko
These fish will produce waste in the quarantine tank and the waste will produce ammonia.
This ammonia is food for the beneficial bacteria which is responsible for the nitrogen cycle.
So it will nourish the beneficial bacteria and keep them thriving in your quarantine tank.

3. Set up and keep all the equipments running
You will need to keep all the equipment such as a filter, a heater running in your quarantine tank.
Ideally, you should try to maintain the same water parameters as your display in your quarantine tank.
It is very important to keep the filter running in a quarantine tank because the filter will not only keep the water clean but is also a very good place for beneficial bacteria to form their colonies.
Besides, when it comes to the filter for your quarantine tank, you should go for a filter in which you can easily remove chemical filtration like Carbon or Zeolite.
This is important because you can also use your quarantine tank as a hospital tank and treat the new fish. And in a hospital tank, you don’t want a chemical filtration because it can remove the medications from the tank.

4. Keep up with the maintenance of your quarantine tank
Though you have added a hardy fish in the quarantine tank, still, you will need to keep up with the maintenance of the quarantine tank to maintain a healthy environment for the fish.
The maintenance of a quarantine tank includes the following things:
- On a daily basis, you should observe the behavior of your fish. Observing the behavior of your fish will tell you if it is doing fine or not. And you will be able to catch any symptoms of diseases at an early stage. Feeding time is a good time to observe your fish’s behavior.
- After about 10 minutes of feeding your fish, you should remove any uneaten food from the tank.
- On a weekly basis, you should clean the inside glass of your fish tank. And do a partial water change of about 30% of your aquarium water.
- On a monthly basis, you should test all the water parameters of your fish tank (ph, ammonia, nitrite, nitrates) and make sure that everything is fine. I recommend API master test kit. It is pretty accurate and it comes with very helpful instructions to use it. You can check its reviews and latest price at Amazon here.
- On a monthly basis, you can also check if any of the filters in your quarantine tank needs to be replaced.
