After a koi fish gives birth, it typically becomes more protective and vigilant, as the newly hatched fry are vulnerable to predators. The mother may also exhibit changes in behavior, such as staying near the spawning area to safeguard the young. However, koi do not provide parental care, and once the fry are free-swimming, they must fend for themselves. The mother may return to her normal activities relatively quickly after spawning.
Koi are egg layers/scatterers of adhesive eggs so they don't actually 'have babies'.
They get along with goldfish but you'll end up with babies that are part goldfish. I have them in the same pond and that's what happened to me. The main problem with putting Koi with other fish, is sometimes the other fish like to eat Koi.
