Well now I'm really worried. I was advised to feed my garter tilapia but never told not to use frozen fillets... She literally just ate a meal of packaged tilapia fillets from Costco. Should she not be fed these? If I have to go out and buy fresh, never frozen, tilapia every week then I would rather just continue feeding pinkies and worms... I don't understand why I was encouraged to feed fish at all of there is such a great danger? Some advice would be helpful...

Thank you
