Goldfish has 'bent' body
Has anyone ever seen this? All my goldfish made it through the winter. However I noticed that one of my white goldfish has a 'bent' body. She barely straightens it out when swimming. Mostly its bent and definetely when she is resting.
Why is this? Is this part of any kind of condition? Could she have been cramped too long in the wrong position in the cold winter water? Last year I brought her inside for the winter into an aquarium to treat for fungus which has been cured more than 1 year ago. Was she somehow spoiled and forgot how to rough out the winter in the pond?
