What do Koi fish eggs Look like. Koī fish are ornamental varieties of domesticated carp that are kept for decorative purposes in outdoor koi ponds or water gardens.
Koi are especially known for the dark brown, white, red, and yellow pigmentation on scales that resemble spots or markings on a tiger.
The variety of colors ranges from white, black to yellow depending on the particular species.
Their coloration can change with age as they grow older but this does not affect their health. When newly hatched koi have no color at all, but after about six months they gain some pigmentation.
As they mature these colors darken and become more vibrant and distinctive patterns appear over time.
This is why it is best to purchase koi from a reputable dealer or breeder, to make sure you get a healthy fish.
Koi hatch in about three to four months. They stay with their mothers for a few weeks before they are typically separated and protected from them by barrier netting.
What do Koi fish eggs Look like
Fertilized Koi eggs look like small beads that are clear or very light brown with small dots on them. If a fertilized egg turns white and appears fuzzy, it is not a good sign. This means that something has gone wrong with either the receiving of the sperm or else there was an accident during the process of insemination where an unfertilized egg got mixed in with the others. Removing these mislabeled eggs from your pond helps improve water quality while simultaneously increasing the chances of survival for ones that were indeed fertilized by adding them to your aquariums.
How to tell if koi eggs are fertilized?
Not all Koi are spawning at once so you will have to check your Koi daily. If they do not lay their eggs within the first 24 hours, it is most likely they are not going to spawn.
Once they begin laying their eggs, most breeders will not remove them from the pond until the fry is seen.
This is because there are many natural predators that feed on newly laid or uncared for eggs and fry.
How many times do koi fish lay eggs?
A common misconception among many aquarium hobbyists is that koi fish lay eggs. This is not true. While some varieties of goldfish are egg-layers, koi are livebearers.
Koikoi have a false organ known as the oviducal gland at the front of their head between their eyes and snout.
Although this looks like an egg, it’s actually used to produce mucus for brooding eggs.
A female koi will actually drop unfertilized eggs if they are agitated or separated from the male before mating has occurred.
These eggs are quickly eaten by other inhabitants in the tank so don’t be alarmed when you see your hard work (and money) floating away down the drain!
The eggs that do fertilize will usually hatch within 14-28 days at a temperature of 72 degrees Fahrenheit.
