When can i start feeding koi again?

When koi hibernate with food in their stomach it can rot and start a bacterial infection that could kill them. Once you completely stop feeding for winter (water below 41 degrees) do not start feeding again until Spring.

When will my koi stop hiding?

For newly introduced fish there is little you can do to prevent them from hiding until they grow used to their new environment. Generally, this behavior will only last a few days, but can be prolonged if the fish is constantly stressed and has no “safe space” to retreat to.

Where do koi parasites come from?

Argulus – The Fish Louse. (Shown Right)It is said that this parasite can be commonly introduced into our koi ponds by frogs and toads. It is however easy to detect with the naked eye especially against the background of fins and white skin of affected koi. Size varies from between 1mm and 5mm.

Why are my big koi dying?

Most of the time, death in koi carp is caused by poor water quality. Making sure you have proper filtration, regular testing and maintenance will all contribute to the quality of your pond water, and therefore the health of your fish.

Why are my koi not feeding?

Poor water quality, or a sudden change in environment, are common reasons koi may lose interest in food. The most common reason for a group of koi to all stop eating at once is a sudden drop in water temperature, usually around late autumn or early winter.

Why are my koi not swimming around?

One of the leading causes of koi immobility is poor water quality. High concentrations of nutrients can stimulate pathogenic growth in your pond and reduce oxygen levels. This can be indicated by strange behavior from multiple koi, although there will always be one or two to first show signs of ill health.

Why are my koi turning white?

As koi grow they’ll change color and pattern, and some may go from patchy all over to totally one tone (often white) after a few years. This is normal and not something you can control, although you can sometimes make better predictions by looking at the fishes bloodlines before purchase.

Why are my pond fish dying all of a sudden?

Sudden phytoplankton die-offs can occur following consecutive days of cloudy, hot, windless conditions. When an algal bloom “crash” occurs, the water will appear to have turned black or clear overnight. The sudden die-off of algae will lead to a rapid decline in dissolved oxygen as bacteria decompose the dead algae.

Why do koi flash?

As a result of the pH change, nutrient overload, and possible temperature fluctuation, koi may begin flashing due to stress and discomfort.

Why do koi lose their scales?

Ornamental koi fish do not typically shed scales through natural means like other fish. If your koi is losing scales profusely, this is most likely a sign of an underlying bacterial infection, which can be dangerous not only to the subject fish but to others in the pond as well.

Why is my koi staying at the top?

If the oxygen level in your pond or tank is not sufficient for the number of Koi residing there, your Koi will likely hang at the top of the water with their mouth opening and closing above the surface of the water. We call this behavior “hurting,” but you may also see it referred to as “piping,” among other terms.

Will a fountain aerate a pond?

Fountains and bubblers are two types of surface aeration systems that work by agitating the surface of the pond to mix oxygen into the top layer of the water. Fountains pump water into the air, creating small droplets that collect oxygen from the atmosphere and fall back into the water.

Will fungus on fish go away by itself?

Fungus needs to be treated promptly because it spreads rapidly, making the fish more vulnerable to secondary infections, such as fin rot. Even by itself, fungus will kill a fish if not remedied.

How to identify male and female koi fish?

The easiest way to tell is from fin shape and color. Male koi have smaller, more pointed fins that are opaque and generally colorful. Female koi, on the other hand, have larger, rounded fins that are partly or completely translucent or even transparent.

How many eggs do koi fish lay?

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.

Are female koi more expensive?

Sexually mature females of highly-valued koi breeds are usually more expensive than males (as demonstrated by Kodama Koi Farm’s fixed-price catalog). They tend to grow larger in size and have rounded fins. Moreover, robust females can produce thousands of viable eggs to ensure their bloodline’s succession.

Can koi change gender?

Koi can be hermaphrodites in addition to being just male or female. Apparently, many fish have also evolved to be able to change sex.

Can koi fish and goldfish interbreed?

Like many interspecies hybrids, koi and goldfish hybrids are sterile. This means they cannot reproduce at all, even with other hybrids. It doesn’t matter if the hybrid is male or female either. Both sexes will be sterile and, as far as studies have shown thus far, there are not exceptions to this rule.

Can koi fish eat goldfish?

Do Koi Eat Gold Fish? Koi could eat small goldfish but it’s not all bad news as they most likely won’t, also there’s plenty of other species that will also happily share a pond.

Do koi lay eggs or have live birth?

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.
