Pet Forum / Aquaria / General / November 2004Koi Carp in a tank is it possible??
I was thinking about setting up a cold water tank with a couple of goldfish and a black moor , a friend sugguested why not get a couple of koi-carp instead , but its only a 2 and a half foot tank. i said it would be crazy to do such a thing , but he said that the fish will only grow there envoriment . Is this indeed the case , or would i be incrediablly cruel to put to very small koi carp in a 2 .5 foot tank ??? >I was thinking about setting up a cold water tank with a couple of goldfish >and a black moor , a friend sugguested why not get a couple of koi-carp [quoted text clipped - 5 lines] > Is this indeed the case , or would i be incrediablly cruel to put to very > small koi carp in a 2 .5 foot tank ???

Also given that the accepted wisdom for healthy Koi in a pond is 1000 gallons for the first fish & 1-200 gallons for every one thereafter I'd say it wouldn't be a great idea!

Iain , thank you , i pretty much guess it would not be a good idea , i though it worth asking , just in case . okay back to plan A , 2 goldfish and a black moor it is.....you just can't beat the black moor shuffle as it swims around.

They do release a hormone that restricts their growth in a small environment, so unless you do major water changes very often or overfeed them they won't outgrow their environment. > Also given that the accepted wisdom for healthy Koi in a pond is 1000 > gallons for the first fish & 1-200 gallons for every one thereafter I'd say > it wouldn't be a great idea! It does work though, I have 5 silver ghosts kois and 8 goldfish in a 240 liters tank with a 2228 eheim filters and a vegetable filter (heavy planted tank with lots of light) in a 100 liters sump via overflows and they haven't grown much for the last year. Don't overfeed them though and keep the temperature stable, my tank is arround 24 degrees celcius and has been stable for the last year... I do water changes every two weeks where I change about 75% of the water (I use a garden hoose to create a syphon), add lots of de-chlorinator and add water through the same hose from the shower thermostat... But if you want your fish to grow to natural size DON'T keep them in a tank, mine are about 4-5" and haven't grown for the last year!!! I feed them once a day but do skip a day or two from time to time, they really don't need much food to stay healthy, they are cold blooded animals so don't use any energy to keep their body temperature above their habitats so only need energy to move around and to keep their metabolism running...
