Wish I could help you, but I don't know much about sicknesses. German Blue Rams are already genetically weak and most are only expected to live 3 months in a home aquarium. Sicknesses are common among these fish, so don't feel like you did something horribly wrong if she does die. You just have to buy these fish from a reputable breeder. Good luck, I really hope someone else can help you here.
