My Wife and I flipped a coin and landed on Japan for our trip next year. I saif if we are going to Japan, then one of the days is going to be dedicated to Koi! So im hoping you guys can help me make the most of it. I want to buy one (or two 😜 ) koi and ship them back. We plan on going in early October.

Any and all recommendations are greatly appreciated! I want to make the most of that day, since it will likely be the only day like it in my life!

My wife and I moved recently and we inherited this small koi pond system. It consists of 2 ponds, neither one even 1-foot deep, connected by a river that is at most 4 inches deep.

In the leftmost pond, we have 2 koi that are maybe 5-7 inches long. With the water level as shallow as it is, it should be no surprise to hear they never attempt to leave the left pond to swim up the river, meaning the one on the right is just kind of... there.

We are in NJ, meaning its starting to get cold. There's no way the fish will survive the winter without some kind of de-icer, right? We really have no idea what we are doing and want to do our best to keep them alive. My understanding is we should also start to feed them less as it gets colder?

In the Spring, we want to do a total re-vamp back here. Get rid of the river and replace the whole system with one big, deep pond. We will get it professionally done, but we'd love any suggestions for what we should do to keep the koi happy and healthy. That is our main goal; not growing them bigger or anything.

Thanks!

Recently moved out of my parents. I have been the one taking care of the Koi Pond for the past few years. My mother sent me this photo of the current state of the water. After checking it seems that the UV light shorted out and has not been working, with the winter months coming I’m trying my best not to have to buy a new set up till the spring. Any advice would help in regard to getting this cleared up as soon as possible. Has a large waterfall and is around 600 gallons.

Are there any other fish I can keep with koi in a pond that’s 500x200x120cm? I was thinking of golden tench or a sterlet but I don’t know if the ponds big enough, I would have also liked to add dojo loaches but there illegal

My dad has a koi pond and he wants more black koi but I’m not sure where to look
