How can I turn baby goldfish gold quicker?

I have a lot of baby goldfish in my pond, they were born last summer and are still brown. I was wondering if anyone knew a way to speed up the process of turning them orange?





I know they turn orange when exposed to full spectrum light but they're outside already, the man at the garden centre said that they give their babies a supplement to turn them orange but I can't find anything about it anywhere.





Any ideas?

They will just have to grow really, as the colour comes with new skin and scales.


However, Carotin based foods should help, if you ask your petshop for a carotin based food. If he doesn't sell them then he's garbage!





DO NOT use any Dying or staining substances, it is cruel to fish, maybe not to maggots, but definately fish!





Carotin is the natural substance that makes carotts orange (hence the name), cooked prawns pink, and the same reason flamingo's are pink, because they digest all the Carotin in the prawns and other shellfish they eat.





Good luck!
