Hi Guys, just think of it, I have been raising rainbow fry for years now and
have *never* bothered with all this fuss. Maybe I am doing it wrong or just
maybe I could achieve better results but many members in Canberra have some
fry that I grew :-) Then again there maybe nothing wrong with what I
do...And I do have a life <g>

Cheers
Alan
