Koi carp eggs typically take about 4 to 7 days to hatch, depending on water temperature and conditions. Warmer water temperatures can speed up the hatching process, while cooler temperatures may prolong it. The eggs are usually laid in spawning mats or vegetation, where they are fertilized and then incubate until the fry emerge. After hatching, the fry will rely on their yolk sacs for nutrition for a few days before they start feeding on small foods.
