Yes, koi fish are typically born black, particularly the fry. As they grow, their colors and patterns develop and can change significantly, with many transforming into the vibrant hues and patterns that koi are known for. Factors such as genetics, diet, and environmental conditions can influence their coloration as they mature.

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.

In Japanese, koi fish is written as "鯉" (koi). The character for "koi" represents the colorful carp fish that are traditionally kept in ponds for their vibrant colors.
Yes my koi reproduce every year. All it takes is maintaining good water quality and providing adequate cover (plants, cracks between rocks etc .) to keep the fry from being eaten. Otherwise you have to use spawning mats and then remove the fertilized eggs from the pond and raise the fry in a separate fish tank until they are big enough to survive in the pond.
