 Fry do not need "baby" food such as brine shrimp or nauplia, though as in adults, plant food increase growth and vitality.Lighting should be strong, to encourage growth of algae; direct sunlight is ideal.In summer, they can be kept in outside tanks, basins, or small ponds in temperate and warmer areas; they can tolerate overnight air temperatures of 60 °F (15 °C) well enough, but should be protected from birds, cats, and other predators.
