Can I add fish after 3 days?
You will need to cycle the tank water for four to six weeks so the tank can maintain a healthy biological and chemical balance. Doing this before adding the fish can help to ensure your new fish stay happy and healthy in their new environment. You can find cycling kits for aquariums at your local pet store or online.
How many fish can you add after a cycle?
A good general rule for most tanks under 100 gallons, never add more than 2-3 fish at one time and no less than 2 weeks in between new additions. This gives the beneficial bacteria foundation time to “cycle” based upon the new addition of nutrients (fish food and poo).

When can I add fish after cycle?
Your tank is close to completing the cycling process when you see a rise in nitrates. It is best to wait until there is 0ppm of ammonia in your tank before adding fish. Once you have 0ppm of ammonia, then you can add one hardy fish such as a clownfish or a green chromis. Be sure to acclimate your new fish to your tank.

- Perform Water Change.
- Add New Livestock.
- Stabilize System.
- Establish Maintenance Routine.
How do I know when my tank is ready to add fish?
Your tank is ready to add fish when your ammonia tests are quickly dropping over the course of a day, and your nitrite level has risen and subsequently dropped back to 0ppm. Once you reach this point, you are ready to add your first fish.
Can I add more fish after a week?
You do not want to add any additional fish to your fish tank until the aquarium has completely cycled – a process that generally takes 6-8 weeks. This means that you need to wait at least six weeks after introducing your first fish before you consider introducing any additional fish to your fish tank.
Why is it important to let your tank cycle before adding fish?
Nitrifying bacteria convert toxic ammonia into nitrite, then less toxic nitrate. Without beneficial bacteria in place inside an aquarium filter, fishkeeping as we know it is not possible as, as soon as you put fish in your tank, ammonia will be excreted and they will poison themselves and die.
Acclimatisation
- Float the bag in your aquarium for 15 to 20 minutes in order for the water in the bag to reach the same temperature as that of the tank.
- Open the bag and add a cup of water from your aquarium. Reseal the bag.
- After 30 minutes your fish will finally be ready for the big move.
How long should my aquarium cycle before I add fish?
It usually take about 3-6 weeks for a new aquarium to go through the initial nitrogen cycle, so fish should be added only a few per week during this time.
How to Cycle Your Aquarium
- When setting up your aquarium, only add a few fish at the start.
- Feed your fish very lightly at first and then gradually increase the amount over the next four to six weeks.
- You can significantly speed up the aquarium cycling process by adding beneficial bacteria from the onset.
