Speed Draw a Koi Fish


Learn how to speed draw a Koi fish. Very talented.

Koi Drawing

Koi and other Fish

I have a large 1/2-acre pond in which I'd like raise Koi. What issues should I address prior to releasing the Koi in the pond? Specifically, will the Koi co-habitate with the existing species, e.g. perch, bass, and bream? -Chris

I don't have much experience with the other wild fish, as long as they are docile, they should get along with the Koi.

Get Rid of Waterfall Bubbles

Pond Bubbles

At the bottom of our waterfall is bubbles like someone put soap in the pond. The bubbles float all around the pond. How can I get rid of the bubbles? - Anthony

You might want to try a protein skimmer. Those bubbles are Dissolved Organic Compounds (microscopic particles of fish waste & other organic debris). A protein skimmer will remove the DOC's from the water, so the bubbles will go away. Click on the above link for more information.

Lump at Base of Fin

Goldfish
One of my koi has a large round lump on the inboard part of each front fin. Can you tell me what it is and recommend any treatment. I have a red Comet fish in my koi pond which has developed a large round lump on the inboard part of each front fin. Can you tell me the likely cause and recommend any treatment. Also, is it likely to be infectious. - John

If the lumps are symmetrical, then they are probably just part of your fish's body structure. If the lumps are asymmetrical, red and infected looking, like these ulcers:
Koi Ulcer

You should get in touch with a veterinarian, get yourself a copy of Koi Health & Disease by Dr. Erik Johnson or try some Tricide-Neo.

Young Koi Spawning

Koi Fish
I have several Koi that are about 6 inches in length. I did a lot of reading before getting them and read that they do not spawn until they are about 2 years old. This morning when I went out to feed them, they were spawning. Is it possible for them to lay eggs as small as they are? One of the larger ones( about 12 inches) was spawning also. They were all chasing one of the 6 inch white ones that I have. -Phancey Phish

It is quite possible that your 6 inch Koi are older than 2 years. They could be the elusive Chiisaigoi or "bonsai Koi".

Koi Fish Simulation

Koi Pond Simulation

You can find a neat Koi fish simulation here. It is slightly interactive, if you click on the pond, it scares the Koi away. It's pretty neat, it'll distract you from work for a while!

Raccoon Proof Pond


My pond is only 2 and a half feet at its deepest point. Will my Koi be safe from the raccoon? -Anthony

Probably not, I would make it deeper with steep edges.

How many gallons of water does each Koi need to have? -Nick

A small Koi, up to 10", should have at least 50 gallons of water per fish. A medium Koi, up to 18", should have at least 250 gallons per fish. A large Koi, up to 30, should have at least 500 gallons per fish. A jumbo Koi, up to 36", should have at least 1000 gallons per fish.

Don't forget to have adequate filtration too!

Scared Koi

I have 4 Koi and 2 Goldfish in my pond. Every time I walk by the pond they quickly dart down to the deepest part of our pond. Am I stressing them out? - Anthony

If you are doing it all the time, then yes. Only occasionally, then no. It is natural for fish to hide when they sense a presence above them. (Think brown bear catching fish.) Koi are different because we train them to lose that shyness by handfeeding them. If Koi were never fed by humans, then they would not be friendly.

Yamabuki Ogon

I have a bright yellow Koi in my pond (along with 3 other koi). I suspect he is a male. How can I be sure? - Bethann

Male Koi tend to be more streamlined and smaller in length.

Koi with Lumps

I have female Koi that is five or six years old, she has not spawned yet. It has lumps on each side of head just below eye line. Has it anything to with spawning or what causes it? -John

From your description, you Koi may have an unusual bone structure in its skull.

Koi and Grass Carp

We have a Koi in our extremely natural pond who is about 18" long and very healthy. (Pacific Northwest). We need to bring in a couple of grass carp to eat the weeds. will the Koi and the grass carp have any problems "getting along?" Thank you for your help. - MaryAnn

If grass carp are docile and non-territorial, then they get along with your Koi. I've had no experience with grass carp, so I don't really have a definitive answer for you. Make sure it is OK to stock your pond with grass carp with your local Department of Natural Resources before you go ahead and do it. Here is some info from the Texas Parks and Wildlife website: http://www.tpwd.state.tx.us/landwater/water/habitats/private_water/gcarp.phtml.

Koi Herpes Outbreak In UK

A KHV outbreak in the UK was confirmed last week by the Department for Environment, Food And Rural Affairs. Read the full story here.

Listing Koi

One of my Kois has stayed in the same corner for 2 days ? A few others are lethargic some are rubbing off the bottom and some are just saying on the surface? They are acting different to normal and when I approach the pond they don't swim away quickly like they usually do? Can you help? -Dave

Sounds like you have a parasite problem. Get in touch with a local veterinarian that's been trained in Koi health.

What type of plants can I put in an outside koi pond? -Tony

You can put any fish-safe non-toxic freshwater aquatic plant in your pond as long as you can afford to feed them to your Koi.

Koi TV

I am interested in your Koi video. Don't you mind if i put your own video in my blog? - Memet

Go right ahead!

What protects Koi from Blue Herons?

What i the most effective way to protect pond koi from herons and egrets? We have had our pond for two years, and we live in an area with many small lakes . . . we have always loved the seasonal arrival of the herons and egrets, but this year they seen to have discovered our pond. While we have a large walkway of about 5 feet, with 2 tunnels underneath, which serve as protection for the koi, we have still lost fish to our feathered fishing friends. We don't want to hurt them, but we do want to protect our fish, who have suffered much stress this summer! Really, what works to deter the herons and egrets?

Here is a few things that you can try:
  • Put netting over the pond until the herons go away
  • Put up a physical barrier around the pond ei rope, high test fishing line, or temporary fencing
  • Try an electronic scarecrow
  • An outside dog will chase away a blue heron

Koi Under Outlet

Hi, I have checked my water it is fine. Nice and clear. I have air in the pond, but the Koi and goldfish are all under the outlet, at the surface. Could you advise please? -David

Did you make sure that you have enough aeration? They one bubbler may not be enough...

How do you tell if a Koi is a boy or girl? -Matt



Male Koi will have a body shaped like a cigar. Female Koi will have a body shaped like a blimp. That is after they reach sexual maturity.

Koi Cut

I had a Koi I bought at 4" and after 4 years he was 8 1/2' and looked healthy. He was in tank with goldfish of smaller size and grow up with them also had Dojo Loaches. My Koi was dead,he had a slit like opening on his stomach. what could of caused this? -Sam

Maybe he cut himself on something in the tank or maybe he pissed off one of the Dojo Loaches.

Turtles

Turtle

I have two turtles 8-10 inches across shell in my pond with my small koi and medium size goldfish. They are okay together. My turtles will eat minnows but don't bother the bigger fish. My pond is 10 X 10 foot square two feet deep and with a 3 foot deep corner hole that is 3x3square I have an aerator running to move the water. -Sandi

When do koi fish have babies?

When they are at least 2 years of age.

New Pond

I have a 10x10x5 pond six weeks old and my Koi keep flicking is there anything i can do? -Alan

Sounds like you have parasites. Get a hold of a vet and have them give you a diagnosis.

Koi in Pond

My pond is about 2500 gallons. How many Koi could I put in my pond? - Peter

You could put around 6 - 8 Koi in that size of a pond. They will seem small for that amount of water at first, but they will grow.

Bubbles on Water

There are bubbles on the top of my pond. They get in the way of seeing my fish. Can you help? -Dale

Get a Clarity Protein Skimmer, it will remove the bubbles off the surface of your pond.

...

So what's your question?

Flicking Koi

I have Koi and they keep flicking what do i do to treat this? Thanks. -Alex

You need to do a microscope scrape and find the parasite that is causing them to run up against the sides of your pond. Then treat the parasite according to what it is most susceptible to.

Swelling on Koi

Fish Tumor

I have a Koi which is about 10 years old. It has a dark swelling to its abdomen more noticeable to the right hand side of the fish. I've spoken to my local fish supplier who thinks that the fish could be egg bound. Could you suggest how the fish could be treated. Egg stripping was suggested? -Reg

It sounds like the eggs have already turned into a tumor. Surgery to have it removed can be done by a trained vet. Talk to some local Koi enthusiasts in your area to find a vet that is knowledgeable about Koi health.
