Hi Rodders and Saph,
Here's a pic of the Goldfish babies I am trying to raise in a 6 gal tank in the house.
They are 1/2 to 1,1/2 inches long and VERY greedy indeed lol

I've lost a few over the last weeks but these ones seem to be doing ok.
Most have changed colour now, I'm feeding them small bits of broken koi food as thats all I have atm, I'm not sure if it's to strong but they eat it all very quickly.
Maybe I should be feeding them flakes ?
