recently i took a few of these babies out of the small tank and put them in

ones outside still have stayed black even though they are bigger than the

determines when they change colour?

Magic.

We have some 5 year old ones that are still black although two of that
group did turn gold and white last year, some will never turn. They
were black originally before they were bred for colour and you always
get genetic throwbacks.
