I have a small pond, about 10x16, and have fish that will not eat food. Last winter I lost most of my big fish, my heater went out, and all to my surprise, their were babies that survived. Last summer they wouldn't eat fish food. I am assuming they must be surviving on algae and bugs because they have grown. I am wondering if I get a fish that has eaten fish food and put it in with them, perhaps they will follow his lead. What do you think?\n\nAlso, all the babies are dark in color with a yellow streak down their backs and around their gills and head. Will they change color, or will they stay dark?\n\nThanks for your answers.
