I woke up this morning to my male betta Benny on the floor! He looked dead, and I immediately scooped him up and put him back into his tank. When I put Benny in his tank, he sank all the way to the bottom and he wasn't moving. My heart sank at that moment and I almost threw up because I was so horrified. Finally after 1 minute he started swimming but he looked horrible. Benny is still swimming but the end of his body and tail look a little white. Is this a bad sign? And if it is a bad sign, is there any way that I can save him or nurse him back to normal?
