Hello, I'm glad I found this channel. I love koi and I've been interested in them since I was 8, I'm 15 now and I'm very happy that I found this channel :) I had my first koi when I was 9, there were 6 of them who lived in my grandparents' garden pond. At that time, my grandparents still had a very small pond, which is why my grandfather, my uncle, my cousin and I built a larger pond. When we finished all the koi were gone, by gone I don't mean dead, they were just Lost. To this day I don't know what happened to them, it was winter so all the koi were at the bottom of the pond we thought, my entire familiy dont know what happened to them. We always had a grid and a net over the pond. I don't know why I wrote this long text but I just wanted to share my experience. That's 6 years ago now we have a big pond and new koi, some of them are over 70cm tall. i just wanted to say i love your channel and think it's cool how much work you put into the channel.

[@TheKoiPartner]

Thank you so much! ❤

[@ry3020]

Someone must have stolen them

[@illegalwaffel6435]

you sure they didn't just die and your family told you they didn't know what happened to them? like most parents do when a pet dies they lie and say stuff like they moved away

[@AdrianA4M]

Birds could have taken them too. They used to catch the gold fish in my pond.

It must be very difficult to film such company's secrets unless you build up good relations with the breeder. Thank you for making such amazing video! Common Japanese people like me do not know about koi much but sometime we find them in the ponds, so this report was so interesting.

I know nothing about Koi except that watching them is extremely meditative for me. I have my favourite colour variations of course, but to me that are just incredibly beautiful fish. I could sit next to a Koi pond for hours. ❤ I’d be very interested to know how to tell the males from the females though.

[@vita123abc]

I have a simple question : why don't the breeders acclimate the kois when transferring from the mud pond to the tank behind the truck? I'd imagine the water chemistry and temperature from the mudpond is vastly different compared to the water in the tank.

[@rolleone6171]

It’s the same water temperature by the time they net the fish out the water

[@TheKoiPartner]

Hi Vita, its almost the same temperature 😊 thanks for the good question ❤

[@gejoei7812]

It is not absolutely necessary to look for an exact same temperature if the difference is not more than 4 degrees Celsius. You don't have to pay attention to adjusting the chemistry of the water either, this is often overrated. Because the stress that the fish have while they are slowly adapting to other values ​​is worse for the koi than if you immediately move them from one water to another and they calm down more quickly. Therefore, never let the bag with the fish swim in the pond first, but place the koi in the pond as soon as they arrive.

[@dpistone10]

Of course another great video. I am doing lots of research before I put a koi pond on my 3 acre ranch. I have so many questions about what type of koi pond I should build. A aquascape pond or a concrete pond? What’s the best filtration for koi? What are the must have’s and the have nots?

[@TheKoiPartner]

The design you should do what you like. I would do a concrete pond. Aquascaped ponds with natural filters (rocks etc) isn’t a good environment to keep koi. Must haves are bottom drains, a good drum filter and ofcourse proper build of the pond

[@dpistone10]

@@TheKoiPartnerthanks for your reply. Do you have any videos that highlight good filtration systems that I should consider? So many choices but I only want the very best and do not want to spend money on things I will regret later on. I would love to see you make a video with the top filtration systems the top hobbyist have used. So many people have spent money on things they regret later on and then they tear them down and start over with different systems. I want to do it right the first time without any regrets. If you have any videos that could guide me please send me the links. Either your videos or someone else’s. I love learning and will spend hundreds of hours on research before I take the plunge. I’ll do this right the first time. Room for me is not a problem. I have three acres here in my ranch and have lots of room to do what ever I want or need too. I just need a great design to copy from when it comes to filtration systems.
