FishFreakAdeline;2103790; said:thats really nice of the employee. but generally petsmart has sick fish. all the tanks are hooked up to one filter and sicknesses can go through all the tanks.
Nearly every major breeder/wholesaler/importer in the country also has 'combined systems'..
It's what goes on behind the tanks is whats important.. (UV sterilizers, carbon, dosing, etc)
