You generally want to wait at least two weeks between introducing new additions to your fish tank. This gives time for the biological filter to get caught up again. This time also allows the new fish to get used to the fish tank, and the older, more established fish to get used to the new additions to your fish tank.
How long should you wait between getting new fish?
If you want to introduce another species of fish after the first one, it’s best to wait for 6 weeks. By this time, any illnesses, infections or diseases should rear their ugly head and be eradicated – and usually, in 6 weeks, the tank’s ecosystem is quite stable to support marine life.
Can I add more fish after a week?
Wait until both the ammonia and nitrite levels have risen and then fallen to zero before adding more 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.

Is it OK to add more fish to my tank?
Adding too many fish to an aquarium at once can destabilize the water chemistry and can cause the nitrogen cycle to stall. As a good rule of thumb only add up to 3 fish at a time to your tank. Once you’ve added the fish to your tank, wait until you’ve completed a nitrogen cycle and then you can add more fish.

How do you know when your tank is cycled?
Ammonia is Not Dropping (Fishless Cycling) If the pH is under 7, ammonia will be mostly present as ammonium which the nitrifying bacteria can’t feed off. Use a pH kit to increase the level. Using chlorinated water will disinfect your tank – killing all the beneficial bacteria.
When should I add bacteria to my aquarium?
You need to add bacteria to an aquarium as often as you add new fish to the tank or change its water. If you change your aquarium’s water once every two weeks, then you need to add bacteria to your tank two times a month. This ensures the bacteria can keep up with the waste conversion.
How do I know when my aquarium is ready for fish?
