How To Care For Small Koi Fish. Feed your young koi four times a day. Keep the waters surface a foot below the breeding tanks top.
So as a person who has kept koi for well over a decade now let me tell what is truly a small aquarium for koi is - and yes this is small. You need to quarantine them in tanks that are at a volume of around 50 gallons per three fish and gradually introduce pond water to their holding water. People keep koi because of their beauty and stunning look.
Most of your kois food will come from what lands in your pond but you can feed them up to 3 tiny portions of extra pellet food a day.
Make sure that the tank is well oxygenated and that the filter is covered with a filter medium to prevent the baby koi from being sucked in. If you plan on using an automatic fish feeder. Add the equipment spawning brushes and the female. My aquarium is indoors climate controlled.
