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.

How long should you wait between adding new fish?

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.

Before acclimatising new fish If you already have fish in your tank, it can also be a good idea to do a quick gravel clean and partial water change within the 24 hours before you purchase the 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.
