I dont think that Pet Cetera fish are bad fish. I know a guy with only Pet Cetera fish in his tank and they are all doing 100%. He added a green chromis from another store and it wiped out all his Pet Cetra fish. He did do the 8 week quarentine (sp?) may i add. It is funny how you can keep these fish together but when you add one from another store they go belly up.
