PETCO must have given them an offer they couldn't refuse. Dr. F&S / Live Aquaria were doing just fine on their own.
Putting on my business cap, I want to believe that Petco purchased Dr F & S for their online business expertise. Hopefully they will be hands off, utilizing their distribution to bring down shipping costs for Dr F & S. The Dr. F & S is too strong to let it go. Just wait and see.
