    These are pictures from a friend who raised 7 fry from this same batch. They were separated at about 1 month old and raised with a traditional water change schedule.

    They were fed a "ton" in a 55 gallon tank with 50% daily WC. He says they are 5" but didn't put them on a tape. 6 are about the same size with 1 smaller one.

    Your friend discus looks much better Luke , which is more or less ,expected .Their colour is much brighter and they have less peppering ,any idea why is that?

    As for the comparision sizes , i didnt get the info on how big have yours grown so far ?
    IMO his discus looks above 5 inch from the pics . More like 5.5-6 inches to me.

    Agreed, imo, his look great.
    One of the pictures I posted of my growing discus should include a tape measure picture. His look bigger.

    I was under the impression that peppering was genetic but with these results it seems like it may also have something to do with water?

    Luke peppering is genetic but its expression is affected by stress and background. Your background is dark...his blue.. it minimizes the expression. Id say his fish look better, probably have better health and as a result ...less stress. The water itself maybe be stressing out your fish.

    I admire your effort to experiment but to me at the end of the day nothing is like fresh clean water.

    Not just for discus but in general.

    Ive run several heavily planted tank's where about 70 - 80 percent is planted. I've had setups where some plants were growing around an inch a day. Even with a heavy plant mass long term success was dependant on water changes. I did a 50 percent change a week. If I skipped one or 2 changes it was apparent.

    I know others will have different opinions but I've never had someone tell me that water changes were bad.

    Out with the old in with the new I say.

    Luke,
    I call your experiment a success, at least for me, I am convinced that big water changes are required
    The debate should be finished, and yes, John from Texas was correct. I should have known it.

    Luke, your thread was solid proof that you can't cut corners raising fry. Your friend got a great deal getting those 7 and raising them. They are gorgeous. This is why I tend to disagree with a previous comment that you should have started with better parents. The one showed some peppering but raised in the proper environment and it turned out to be a non issue.

    My question now is what happens to all these poor fish?

    Thanks for sharing this with us. It was definitely interesting to see.
