Entire school or just a few?

    When adding schooling fish to an aquarium, are you supposed to add the entire school at once or only add a few at a time? If I'm only supposed to add a few at a time, how long should I wait between each addition? It'll be a school of danios if that makes a difference in your answers. Thanks in advance for your responses :]

    I usually add my school all together. Like for example when I got my neon tetras I only added 5 of them. Then i started adding more of them 1 at a time

    In my 29g tank, I added 12 Longfin zebra danios all at once, all seem fine. Didn't have a noticeable spike in water parameters!

    Personally for me it depends on the size, around 6 all at once around 10 ill break it up.

    It depends on how much effect they will have on the filter, which is dependant on how much you will increase the feeding. If its going to double your stock/feeding, then I'd do it a few at a time. OR increase the feeding gradually, to 'smooth out' the increased load on the filter.

    I added my 6 neons all at once so I guess that's a good number because I didn't have any spikes in parameters

    Thanks so much for your help. I feel a lot better about adding like 6 fish at a time now
