I can't believe he is gone and the one I bought just before christmas is dead. I am a very responsible fish keeper. I have goldfish, first 2 started in a 3 gallon which was not cycled and they are still with me after 21/2 yrs. I have tropical fish, and puffer fish which is still with me, I bought her early last summer. Why are my bettas dying. I have and expensive betta coming from Thialand, the transhipper just recieved him today and I will have him on Wednesday. I don't want him dying. I want to get one more to replace Rainbow for the 10 gllon divided. But now I am afraid that I will have them dying too. I take care of them, the tank is cycled, filter is covered with pop bottle cut in half so not so turbulent for Flame. I do everything for my fish but the bettas are not surviving. I hope no other fish die, I hate it.
