We unexpectedly had baby koi after both parents had died. We watched pregnancy and fertilization, but both parents then died for unknown reasons. What do we feed the babies- they are about 3 inches long.

At 7 days of age you can start feeding a special Koi fry food consisting of fine powder pellets. As they grow you can gradually increase the size of pellets. Be sure to only feed special Koi food with high protein content. Do not over feed. Your fish should eat as much as they can consume in about 1-2 minutes 4 times a day.
