It is best to keep them in the tank or separate pond until they reach about 3 inches to prevent other fish from eating them.
How do I know if my pond fish are pregnant?
Look at the females carefully for any signs of swelling, which could indicate that maturing eggs are inside her. Females will also eat more food than the males during this time so that they can produce successful eggs (see Reference 1).
What time of year do koi lay eggs?
Spawning season usually takes place in the early mornings during May and June. As the koi prepare to spawn, the males will start following and showing interest to the most receptive and fertile female.
Is my koi fat or pregnant?
K.O.I. This user has no status. Well, koi are never pregnant. Their ovaries contain eggs that they will expell and the male will fertilize.
Will a female koi lay eggs without a male?
Yep, females WILL release eggs with no males present.
Will my koi have babies?
Yes, that’s right, sooner or later the fish in your pond are going to have babies. Around late spring to early summer, koi and goldfish start spawning. As the fish spawn, they reproduce thousands of eggs. Only a few of them survive and become baby fish.
What does it look like when fish lay eggs?
Once laid, the eggs often look like tiny balls of jelly. These are often scattered to the water, but in some species they end up in a mound on the nesting area, or stuck to the floor or side of the aquarium. Many egg-laying species also have mating rituals, including most gouramis.
How does koi fish eggs look like?
Koi eggs look like very small beads that can vary from clear to yellow or amber. Some compare koi eggs to tapioca pudding. If you notice eggs in your koi pond and they are black instead of clear or amber, you likely have toad eggs. And there will be a lot of them.
What to do when koi is pregnant?
However, your koi will appear bloated and pregnant for up to several days before she’s ready to release her eggs. At this point, you could still stop the spawning from happening if you don’t want eggs or baby fish (fry) in your pond by simply removing the females from the pond, keeping them separate from the males.
Why are my koi flashing?
1) Koi Flashing After Food
Sometimes, the gill rakers (located on the gill arches, and functioning as a food filtering system as the koi eats) become clogged with food when eating. This can result in koi flashing behavior, as they work to free their gills of this excess food.
Can koi mate with goldfish?
Koi will breed with the goldfish. Some of the baby fish (fry) will be born brown or grey and may turn orange as they get older. These fish will not be pure koi, something that doesn’t really matter unless you are really into koi! Koi have whiskers called “barbels” while goldfish do not.
How long is a fish pregnant?
As examples, the female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.
Why is my koi fish stomach so big?
Swollen Belly
The fluid accumulation is caused by the inability of the kidneys and/or gills to eliminate water from the body, which is a result of the underlying health problem.
Why does my koi looks bloated?
If a koi has advanced dropsy, it is very noticeable and recognisable as the fluid inside the koi’s body will cause it to swell and bloat. As the body swells more and more, the scales will develop gaps between them which will make them lift away from the body of the koi.
How long does it take for koi eggs to hatch?
In about two to five days, the eggs will begin to hatch, and baby koi, known as “fry” will emerge. After her part is complete, the female koi will begin creating new eggs. These will be laid in about a year’s time, as that’s how long it takes for them develop.
Will koi fish eat their babies?
The simple answer to the question of whether or not koi eat their young is yes, they are known to eat their babies. However, they don’t necessarily do it on purpose. As omnivores, koi eat both plant and animal matter, such as algae, bugs, and flies.
How many babies do koi fish have at a time?
How many eggs do koi fish lay? A 2-pound sexually mature koi in her prime can lay up to 100,000 eggs during a breeding season. Professional koi breeders usually estimate the number of eggs by monitoring a female koi’s weight. For every 1 pound of body weight, a female koi can lay 50,000 eggs.
Do koi fish lay eggs or have live babies?
They don’t give live birth, and the eggs are fertilized outside of the body, so there really aren’t baby koi in your fish either way. However, your koi will appear bloated and pregnant for up to several days before she’s ready to release her eggs.

It’s Spawning Season for Zoo’s Koi Fish
Updating One of the Zoo’s most beautiful exhibits is one that most guests don’t notice on initial glance. The Zoo is home to a group of stunning koi fish that swim among the ponds that weave throughout Bamboo Trail. Koi are known to get along very well with little to no competitiveness or aggression toward each other. However, over the last two weeks, our group of Koi were making it a little bit harder to go unnoticed with fast chasing and swift splashing. IT’S SPAWNING SEASON The chasing and splashing were a result of the Koi spawning. Spawning season usually takes place in the early mornings during May and June. As the Koi prepare to spawn, the males will start following and showing interest to the most receptive and fertile female. When it’s time for the female to lay her eggs, the males will start frantically chasing her around the shoreline of the ponds and nudging her side with their mouths. EGGS, EGGS, EGGS Like most fish, Koi are egg layers. A mature female can produce up to 100,000 eggs. Once the female sheds the eggs, they will stick to whatever they come in contact with. As the eggs are shed, they are immediately fertilized by the males that are following her. While females lay thousands of eggs during spawning, most of the eggs are eaten by other Koi in the pond. In attempts to save some of the eggs, Nashville Zoo’s aquatic team placed green filters inside the ponds so we could collect the eggs and move them to an isolated area of the pond for hatching. SPECIES HISTORY While they are admired for their unique colors and markings, the history of Koi fish is not commonly known but is very elaborate. Koi, or Nishikigoi ( Cyprinus carpio ), are descendants of the common carp. In nature, they are brown, but through selective breeding by the Japanese, numerous colors and patterns were developed. The beautiful coloring of the Koi is actually a mutated form of carp. Although the Japanese specialized in the selective breeding, the true beginning of Koi fish originates in China when the carp started to develop patches of colors (like white, red, and blue) in their natural habitats in the Black, Caspian, and Aral seas in Asia. - Table of Contents:

Is My Koi Pregnant?
Well, this time of year, it’s definitely possible. Spring is when koi generally spawn. I’ve written before about how to determine the sex of your koi as well as how to get your koi to spawn, but how do you decide if your koi have decided to get spawny without your intervention?
Well, first off, it’s worth noting that a koi that appears pregnant is not, one way or the other, pregnant in the same way that a human would be. They don’t give live birth, and the eggs are fertilized outside of the body, so there really aren’t baby koi in your fish either way. However, your koi will appear bloated and pregnant for up to several days before she’s ready to release her eggs. At this point, you could still stop the spawning from happening if you don’t want eggs or baby fish (fry) in your pond by simply removing the females from the pond, keeping them separate from the males. This shouldn’t hurt the females (assuming that you keep them in good conditions). Without males to agitate her into releasing the eggs, she’ll just reabsorb them as protein. She’ll also do this if you simply have no male koi in your pond with whom to mate.
If your fish is full of eggs, she’ll catch the eyes of the males around her and they’ll start to chase her around the pond to get her to release the eggs. This can get quite rough, though your females are likely to be fine, as they’re generally larger than males. The males will push against her sides, and eventually she’ll release her eggs into a protected area, usually among vegetation. The males will then release their milt over the eggs. Often several females in the same pond will have eggs at the same time, but usually only one female per day will actually release her eggs.
At this point serious koi breeders will remove the eggs from the pond to protect them (koi tend to eat their own eggs as well as fry). This isn’t entirely necessary, though, as some of the eggs are likely to survive either way. Be prepared, though, as generally very few fish will survive to adulthood.
Pregnant Koi Fish

“Pregnant koi” is a term for female koi who are filled with eggs they are ready to lay. Koi do not get pregnant and are not live-bearers. Koi fish typically mate in warmer water in the spring or summer seasons. The mating period lasts about two to three days in which the female lays the eggs upon various surfaces while the male shortly after fertilizes them.

Carrying Term

Female koi start to carry their eggs around wintertime for a few months until the mating seasons comes around. They carry several thousands of delicate, translucent eggs and will feed more eagerly than usual during the egg-carrying period. Do not expect this from females less than three years old, as koi are not fully mature until this time. Younger koi can breed, but the quality of the offspring will be quite low.

Appearance

The appearance of a female that is carrying eggs should be very noticeable. The female will have a bloated appearance that will seem one-sided, usually the left side. She will noticeably larger than the male koi. If you notice this appearance in an immature female koi, or late in the mating season, it may be indicative of disease or some sort of parasite.

Spawning

When you notice your “pregnant” koi is engorged with eggs, help her out by providing areas to lay her eggs so they can be easily collected for incubation afterward. Use nylon rope cut into several strips, each a few feet long, and secure these along the pond walls as a resting point for her eggs. Koi will pick up on this fast and prefer a soft area to lay their eggs in comparison with a rough, hard surface.

Signs that mating will soon take place are seeing the male nudging and rubbing against the female. The actual spawning itself is brief, lasting about half an hour. A sign that the mating has already occurred is observing a foamy like substance on the surface of the water. The female will also appear to be exhausted.

Complications

Sometimes female koi can fail to release their eggs. The eggs can reabsorb over time, but this is a slow process. Unreleased eggs can cause infection in the fish such as septicemia, and the results can be life-threatening. Many owners will have a professional manually remove the eggs before breeding as a safe breeding alternative because of the breeding process, which can pose harm to the fish. The breeding process can be pretty rough on the female koi; males may injure the female as several of them may go after the same female. Injuries can occur while the fish are working at expelling the eggs or during the general spawning period. Wounds and missing scales are common after the breeding process. It is important to keep a watchful eye during the spawning period because males can also become overaggressive, and fish may need to be separated.

Egg Care

After the mating process, remove the ropes keeping the eggs intact and house in an aquarium or separate pond to protect them from being eaten by other adult koi, including the parents. They will do well in at least a 100-gallon tank with only a few inches of water. They will hatch in about three to four days and will not begin to swim until they are about two to three days old. It is best to keep them in the tank or separate pond until they reach about 3 inches to prevent other fish from eating them. During this time, feed them brine shrimp larvae, brine shrimp and crumbled koi flake food.
How to Know When Pond Fish Are Having Babies
Things You’ll Need Aquarium or pond thermometer
Spawning mops
When fish have babies, it is known as “spawning.” The baby fish produced from spawning are called “fry.” As long as there is a male and a female, pond fish will spawn if conditions are right for rearing fry. There will be signs leading up to the event, but the actual spawning can easily be missed since it may only last for 20 to 30 minutes (see Reference 1). Eggs should appear in the pond if the fish are successful, and the fry can be raised if desired.
Check the calendar. Pond fish begin their breeding cycle when the days begin to get longer and the water temperature is starting to rise. The long days of early summer stimulate the females to prepare her eggs for spawning (see Reference 1).
Get a pond or aquarium thermometer and test the water’s temperature. Koi fish will breed at 68 degrees Fahrenheit (see Reference 1), but both goldfish and koi will spawn if the water temperature is gradually raised (see Reference 2), signaling the warm season.
Determine the age of the pond fish. Koi should be old enough to have reached sexual maturity at around two years old (see Reference 3).
Look at the females carefully for any signs of swelling, which could indicate that maturing eggs are inside her. Females will also eat more food than the males during this time so that they can produce successful eggs (see Reference 1).
Watch the male fish behavior. Around the time of spawning, they may swim in groups along the surface of the water or the edges of the pond (see Reference 1).
The males will chase the females around the pond and attempt to beat the eggs out of her when the fish begin spawning (see Reference 1).
Check the water for clear eggs. They may be under plants or cling to other things in the pond water. The adult fish may eat a number of the eggs before there is a chance to check the water. Spawning mops can be used to catch the eggs.
Tips To keep the eggs alive, they must be removed from the adult fish’s pond to protect them from being eaten. The eggs should be put into a separate rearing tank or pond.
