PH level and temperature adjustment are the first things that come to
mind. Did you check the ph....was the new the same as the old waters
ph? Was the temps the same and did you float the fish to acclimate
them to a possible difference in the temps? Did you use any type of
detergent to clean your pond? Was it thouroughly rinsed and free of
any possible residue? Did you use sufficient chlorine remover?

Not an expert by any means but I would wonder about the things I
listed if it was me.... Nothing else has really changed but the water
change and it has to be with the water, at least I would think so.
