Ok, so I've got a pond in the back, which I've had for years with some Koi and Goldfish. Every winter ill bring them inside into a 50g ive got sitting in the basement. During the beginning of the winter is usually when I buy my koi, they are cheaper and lots of people are getting rid of them this time of year. We all know that koi grow fast as hell in ponds, my question is how can i make them grow faster inside? I know warmer temps help, so ive got the tank heated. Theres a high flow rate, waters moving quite fast all the time. Lights on, and tonnes of air being pumped into the tank, lots of little tiny bubbles everywhere! haha
How can I make these fish grow fast!!
Thanks, any input is appreciated!
