Allan, your fish bright orange? I have also heard of vendors feeding lots of mysis right before a photoshoot to boost colors. I only saw gradual changes though and after a week of heavy feddings a noticable difference in the brightness of the oranges.

Not sure if you saw my comment... but some breeders say a heavy mysis diet can cause eggs to be delayed in hatching.

My eggs hatch and the broodstock fish get mysis from the rod's food, but I used to feed only mysis which could have been causing me some problems. Not sure...because only recently thought of it.
