Koi Corner / Koi in an aquarium

« on: October 26, 2009, 07:24:02 AM »

Just for winter fun, I brought some small koi indoors for a new aquarium, 26 gal, with filter, rock, plastic plants,  etc.  I have 17 in there. Most are about 1 inch. a few are 2 and 2 1/2 inches long. I brought them in from my mud pond where I have a couple thousand from this year's spawn. The pond will freeze over in a couple of more months here in NE PA. A couple of questions: Is that too many for an aquarium this size? Can I limit their growth by feeding less...or should I even try to do that? I'll probably put them back outside when the ice goes out in mid March.  John B

Koi Corner / growth rates

I built a mud pond just prior to my koi spawning on May 23rd and 24th. I added eggs to my new pond on those dates only. As the summer went along I noticed a great difference in the size of the young fish. Presently they are still feeding at around 60 degrees water temp. My question is why is there such a large difference in size? A few are 6 inches long and almost  (estimate) a quarter pound. Most are 1 1/2 to 2 inches long. Many are small, barely 1 inch. All appear to be feeding and healthy. I'm guessing some of the eggs fell to the deeper and cooler portions of the shallow pond last spring and got a slower start?? The pond is 2 to 4 1/2 foot deep and 35ft by 70 ft.  John B
