My husband and I have always like fish, we decided to go bigger changing from fish tank to a pond. He personally build our pond, it's about 1400 gallons. He have kept it running for about 8-9 years now. He have koi and goldfish although one of our goldfish has been pregnant for a while, maybe since summer or 2015 and were not sure what to do. Any suggestions, I touched her tummy and it feels soft . I don't show any of the males after her or anything. She does not seem like she's sick.. Here is an image of her. Please if anyone can respond on what should be done it would be greatly appreciated. Thank you. Lourdes
