So far I have had two negative experiences with betta fish but I love them so much.
The first was a red betta fish that my fiancee bought for me, she was gorgeous and I named her Sparky. She wouldn't eat the flakes or any other type of food so she ended up dying.
Then on the 22nd of December of this year we tried again, we bought a beautiful blue/green half-moon betta fish. He was absolutely stunning. We named him Jazz. We had him for three days and at first he seemed really happy, active. But then on the second day I noticed he stayed near the top of the water. Yesturday he swam to the bottom of the tank and just stayed still. Jazz had died.
I called the petstore demanding to know why this poor little fish died, when I had checked and rechecked that I had done everything right. He said to just bring the fish in and he would exchange it for another one.
But I need pointers on what to look for. He says the store only has one half-moon left, a blue-green one. But Im worried if I get this fish, will it just happen again? I dont want my fiancee broken hearted.
