    To be honest to start a juvenile Koi you should start with a tank no smaller than 55 gallons and that’s only for over wintering, they will grow fast, up to around 2″ a month when small, they will get 12″-14″ within a year, and 24″ plus within 2-3 years.

    Koi are strictly pond fish, fish tanks are the wrong dimensions for these huge fish. For a tank anywhere near the right dimensions it would be a couple of hundred gallons, over 300. But really they need a pond a minimum of 1,000 gallons.

    Five minutes.
    Seriously, you can’t house a butterfly koi or any other koi in a 16-gallon tank. Don’t even think about it.
    An adult koi should have a pond of at least 1000 gallons.

    There are many small fish you could keep in a 16-gallon aquarium. You might like some of the smaller barbs, which are related to koi.

    You should be fine, until it reaches 15 inches.

    Never.

    How long?

    Long enough to get a much bigger tank cycled is about all.

    A young healthy Koi should be growing about an inch per month – so is going to get too big for that tank in a few months, or else you are going to start stunting it and affect it’s health.

    Good size tank if you can’t put it in a pond? About 500gallons!!!

    Seriously don’t buy a Koi unless you have a plan on what you are going to do with it in a couple of years time. A shubunkin goldfish looks very similar, but wont grow as big. You could start one out in a 16gal, and move it to a 55gal for life as it grew.
