adding more fish

[Mle77]

Hello, I recently had a spike in nitrites, and now have that under control. I am trying to stock my school of Mollies (I currently have 4) and would like to have 9 to 10. How long should I wait (being as I just got nitrites under control yesterday,) to add more Mollies? I plan to add 3 at a time, 3 more times.
Thanks!

My fault, I have 4 and want to add 3 and then 2. Or can I add all 5 at once?

Do you have a reading for nitrates?

 

[Mle77]

Yes, they are at about 20.

If it were me, I would wait to get straight readings of 0 for ammonia and nitrites for a few days before adding fish (I waited 5 days), then I'd add 2-4 a week But, I'd keep up with water testings everyday until the tank is well established.

How big is your tank? Mollies have a big bioload, so all at once could really shock your tank unless it's pretty big. I would add only a few at a time.
