Gina, I'm sorry you lost some of your fish. It's very hard to find healthy goldfish. Years ago I went through one after the other until I got one to live, and even it had ick but I nursed it back to health. She ended up living 5 years!
I recently bought two goldfish and one lived so now the game of moving to bigger and bigger tanks and maybe trying to get him a friend. His name is Lucky!
