I was conditioning male betta since 2 months. Feeding him small amount of food 3 times a day. I tried to breed him but he was not making bubble nest. So i kept conditioning him to give more try. But every time he is not making bubble nest when i place female near him.he was only flaring but previous time he made bubble nest and gave good colored fry.now He became more bulky and less active. Now he is fading his color from body. How to cure him?
