Patrick,

In the shops around Sydney, the rainbows don't often have much colour. And
even when you get them home it seems they take a while to settle down and
show their true colours.

However, it seems logical that if any fish is continually in-bred, that
flaws will start to appear.

Cheers,

Michael
