Well, it didn't take long to fill the fish bowl again. My granddaughter got to get a new fish today. She named it Max. Max is a much smaller goldfish than Dorothy. Max swims fast and zig zags through the water with much speed. Dorothy was a very slow graceful swimmer.
I looked up some information about goldfish after Dorothy died. Goldfish can live 10 years or more if you take proper care of them. They can grow to 6" in length. Experts don't recommend a fish bowl because they don't get enough oxygen. They say each goldfish needs 10 gallons of water! If you feed them dry flakes, you should soak them in water for at least one minute. The dry food can expand inside the goldfish. When the fish goes to the top to gather the food, it creates air in their swim bladder (which could cause swimming bladder disease; floating). They can also be fed tiny amounts of fresh foods: Romaine lettuce, cooked peas, earthworms, eggs, cucumber, grapes, oranges and spinach. Besides the flake food they can be fed: Krill, Plankton, Brine Shrimp, Blood Worms, Spirulina and Daphnia.
I discovered that the food (TetraFin) that I was feeding Dorothy contained artificial colors: Blue2 Lake, Red 3 Dye, Yellow 5 Lake, and Yellow 6 Lake. It also contained the toxic preservative, Ethoxyquin. No wonder she died before her time.
I purchased a new food for Max. It is made by Wardley (Hartz Mountain Corporation) and does not contain artificial colors or preservatives. Welcome to our home, Max.
