    What is the appropriate time to wait between adding fish to your tank? As in if u added 2 fish today what would the appropriate time to wait before adding another one and so on.
    Does it depend on the size? Does it depend on the type of fish? I have read and heard different opinions on this.

    Don't worry its not me trying to rush into stocking my tank :)

    So u think Dallas, that as long as your parameters are fine u can just keep adding fish? well obviously till u reach your limit the tank can handle.

    well i would assume that once your readings are back down that the bacteria have adapted to the new bio-load, so thats what i would do

    I would say at least a minimum of 1 to 2 weeks before adding livestock longer if possible. You need to give your tanks biological filtration time to catch up to the added bio-load.

    If you add more than 2 fish at once, wait longer then after adding 1 fish. Size and type can affect the time. Larger fish add greater bio load, so you need more time between adding more livestock.

    That is about the size of it, when you add a fish, you add to the bio load, the bacteria multiply to the new conditions and your tank settles down again, but give it a couple of weeks minimum, don't forget the new fish need time to settle down and get used to their new environment without the hassle of your extra attention around the tank.

    No, some people might take it wrong. I mean you can test your water now and if it tests ok you add fish, now tomorrow you test again and if it tests fine you add more fish again - not the right way. You will get an ammonia spike if you add too many fish too quickly because they need to eat and they poo and all that (ammonia) needs to be converted to nitrites and then to nitrates, then your DSB still needs to convert the nitrates to nitrogen (If you have a DSB and is matured enough). I would say wait 1-2 weeks before adding more to give the bacteria chance to do their magic ;)

    I know you did, not aimed at you ;) , the only reason I mentioned it is for beginners not to take it up wrong... and believe me, there are people like that on the forum. He will test his water ten times a day and keep adding fish because the water still tests fine - only to have a crashed tank a few days later :(

    id say a rule of thumb is one smallish fish per 30 -60 days depending on tests over a period of 30 days inbetween additions... remember effects of what you do today may only become aparent tomorrow or in a months time... also half the fun is in adding the fish so why rush it.... also be wary of unplanned for addition.. fish caught in the season are "free" and will most definatley be added.. the problem is that the load they bring with them could cost you your whole system.
