So, many of you have been helping me in treating my boy with the bad fin and body rot over the last 3 months, but it is now much worse. I have tried many courses of many medicines and in the end to know avail. After much thought, sadness and consideration mostly on his part, I have decided it is too far gone and I can't stand to watch him suffer anymore . he is just rotting away in front of me each day and it is heartbreaking. I know what I am asking is not an easy thing but Iwant to humainly uthenize him now. Yester day when I looked his back rot had spread alot since the day before and is open and red and today again worse and that is with treatment in perfectly clean water. So at least this way he will be restored to a painless version of his former beauty andwill swim aaround in peace with all the fishies under the rainbow bridge. Please help me, tell me how I can do this for him. Thank you very much for your help. Sad mommy to Calypso my avatar. My almost 4 year old betta and I will miss him and his beauty.
