Koi in a tank

[aquaculture]

Keep the koi in a tank or pond just as long as its appropiate in size, and water is clean and fish is stress free enjoy it.

FIsh are meant to live in water,in a kois case freshwater, weither pond or tank, KOi are meant to be seen with eyes from whatever angle, To think having a koi is for eletist snobs is not right and its not right to enforce views of eletists espeacially about large colorful fish, when they can live just as long and healthy lives in the right sized tank or right sized pond with the same requirements for all fish, clean water, space, a stress free environment.

CONCLUSION:
Get a Koi just keep it healthy and happy in a Tank or Pond.

9x or 10x turnover sounds pretty sufficient. Be ready for extra aeration, too, since room temp is a bit warm for koi. In a 200, I'd think two koi would be a manageable number until they reach about a foot each, but the nitrates will tell you for sure when it's time to move them to bigger quarters.

I know why you want them. I have a koi in quarantine downstairs and it's just like an Oscar. Wish I could keep him in a tank for awhile. GL.

That's not the point. They are POND fish... You don't keep a Great white in a Bath Tub, why would you keep a Koi in a tank?!

Why is it unacceptable for Koi to be in tanks, yet it's ok for RTC's and TSNs(which get much bigger) ok to be in tanks?

And don't give me the coldwater argument as right now my pond IS hotter then my tank.

A monster is a monster. Whether in a tank or pond, water volume and type/amount of filtration required for a given species will be similar. Temps and other adjustables can be made to suit the inhabitants as desired.required. I've seen ponds smaller than my 125g tank. Just saying.

Koi can live up to 200 years... keeping them in a tank will greatly lower their life span.

I wish there were more people like you out there........FOR EVERY1 ELSE KOI ARE ABLE TO GET TO 60IBS!!!!WILL A 200GALLON HOLD THAT!?

We have a local dining establishment and they have been keeping KOI in a tank for about 10~15 years. Their oldest fish is 10 years old. We've talked to the owner about what they do to maintain the tank. They have about four 15" fish, two 8". In about 200 gallon tank. They change 70% of the water every week. And have very high flow filters. They don't take any chemical readings, just change the water frequently, and add DeChlor to the water. We get Chicago city water here so lots of chlorine in the water. It can be done, the fish are healthy and active. Would they be better in a pond, sure, but they have a pretty healthy color and are active. Definitely well cared for and healthy

I think a 10 year old koi that's only reached 15" is pretty stunted....which wouldn't make it a healthy fish.

Koi, goldfish, carp, etc seem to produce MUCH more nitrates than most other aquarium fish.

Thanks for all the KOI and big fish info. I have a test kit and will be monitoring chemical levels. And as the fish grow it will be come an excuse to build a pond !!! I was at Tasty Cuisine last night, the biggest Koi probably was bigger than 15". They change the water every week, so I guess if you are willing to do the maintenance you can be successful. Plus putting it in your business makes it a business expense!!!! Now that's the way to do it.

Wow.....can fishkeepers really make the argument that a certain fish belongs in an outdoor pond? The same argument can be made that whatever you have in your tank, doesn't belong their either. Taking wild fish, even if it's tank bred it came from somewhere and putting it in a glass box, in your house, and hand feeding it, so natural i'm sure. Get over yourselves and contribute something positive to the conversation

I have a few high quality koi in a 6 footer atm.

Setting up some photo sensor lights for him now in the pond.
