When can my baby eat shellfish? Shellfish can be a healthy part of your child's diet soon after she begins to eat solid food, usually when she's around 4 to 6 months. But if your baby has chronic eczema or a food allergy, talk to the doctor first before giving your baby shellfish.
One Month to One Year. At one month old, baby goldfish can eat regular fish food, ground up for their size. At four months, they no longer require ground-up food. Again, you want to siphon out anything they haven't eaten after the first 20 minutes to keep from polluting the water.
