Almost a year ago, about 5 days shy, I bought Aidan and Owen 2 fish. They are beta fish, so I had to get a special bowl to put them in. If they are in the same tank they will kill each other. Aidan was so good about the fish, at first! He quickly lost interest, and to be honest so did I Many times I thought the fish was a goner, but I would change the water and voila! The fish would come back. We knew the fish was going to die because he/she spent about a week only moving when we tapped the tank. I had to wait until the fish sunk to the bottom to convince Aidan it was dead. I thought he would take it hard, but he did not. He said , "It's ok....that fish was Owen's!"
