Dan, I dont believe Taffy meant anything as a personal attack on you. Taffy is very experienced with these little guys and anything he says I personally would tend to take what he says as good information, maybe something to think about or apply in the future if you want to improve the quality of your stock.
Since you say that the water quality is the biggest factor in causing deformities etc, then if it was me, I would tend to try and work on the water quality in the adult tank. If Taffy is right (and I would have NO way of making a judgement on that one way or the other) then having clean water on the adult tank, and being able to leave the fry with the parents would yield the healthiest fry, right?
I agree with Orion...your pictures are wonderful! I'm totally jealous. What kind of camera do you use?
