Hi, my name is Karrina and I am a mother to a preschooler named Delilah, and I am expecting a baby November 15th. We have one tank with 2 in it. One is a common goldfish and the other is a redcap oranda. We hope to get more fish soon. I joined this website because we have been having some trouble with our fish, and we would like to share our experience with people who have had the same problem.
