Just a simple note on diet:

For what it is worth, the feed I give my fish is a mix of 25% dried
plankton, 50% dried blood worms, 50% spirolena algae. This seems to be the
best mix I have come up with without doing the pumpkin and peas bit. The
fish seem to be doing much better on this diet than any other I have tried.
I do also about 4 times a week suplement the diet with a good feed of
frozen brine and bloodworms mixed. This is a costly way to feed but the
adults are almost allways in breeding condition. Durring breeding I feed
exclusively the frozen brine and bloodworm mix. I have not experienced
getting "sick eggs" with this diet.

The term "sick eggs" is a term I use to describe the eggs from fish that
have not been fed an apporiate diet thus resulting in fry that are not as
strong as they should be due to the lack of nutrients in the yolk sack. The
health of the fry is a direct reflection of the diet feed to the adults.
Argue if you want but I agree with Adrian, diet is the single most
important factor in keeping rainbowfishes.
