Aww sorry to hear that Linda. Like parting with an old friend.
I had some plants that did similarly..one a succulent, thankfully I was able to get some cuttings, before mommy plant bid adieu. My Dracaena sanderiana also did a swan song after 7 years, but I have not given up on a stalk cutting yet, but the main plant is gone.
I have not grown goldfish plant..hope you can find a replacement this Spring.
