Answer
Hello,

Well your bowl is your problem.
Bowls can cause stunting, where the organs grow but the body doesn't, it is also a toxic nightmare as goldfish need filters as they produce ALOT of waste and it turns there tank into a toxic noghtmare if there isnt a filter, in a bowl you should do water changes every other day, but they can still die due to the small space.
The only thing you can try now is doing a 50% water change, but im not sure if she will make it, im really sorry, if you want goldfish in the future please look back on julliet and think about what your doing, NEVER keep them in a bowl, they supposedly need 20 Gallons each and a further 10 gallons for each additional one but 10 Gallons for one or 2 small goldfish, but remember they grow!
