Maybe the control group could follow what we all follow today to raise our discus - hobby standard. Considering the amount of participants needed, time, effort, and the amounts of fry that would have to be donated, I'd go with Al's idea to slowly collect the data we essentially want from your experimental method, but in a slower scale. What I understood from Al was that he wants to test one or the other. Either Holding WC's constant and changing the foods or vise versa. This method requires about 8 participants.
I'd love to participate on this spring challenge. I wish I could donate fry, but my pair are not good parents.
