Goldfish do not get pregnant.
You can continue to keep, and care for goldfish while pregnant. Goldfish are not edible, at least not to humans, so as long as you are not eating them, you will be fine.If you mean the goldfish crackers, then those are just fine to eat as well.
There is nothing unsafe about caring for your fish while pregnant, so you can continue as normal
While it's possible that many types of fish may appear to get along, they are not compatible. Goldfish and gouramis should not be housed in the same tank as their needs are different. Goldfish are best living with goldfish.
Any types of meds taken while pregnant you have to discuss with your doctor. Especially meds for that!
Some goldfish are male, while others are female.
While a goldfish may have a chew on something that falls into your tank, it's not recommended to purposely feed them spiders (or flies, or any other bug).
No, do not eat activia yogurt while pregnant. Just eat the other kind of yogurt.

We have had 2 hatchings of goldfish and they usually start changing to gold, or any other colors that they will be, at a month old, and will continue to change color while they grow.
Please do not feed a goldfish cheese. While they may eat it, it is not good for fish. Fish do not have the ability to break down animal fats like humans or other animals.
Tums or other antiacid
