Our old male, Gorton, is getting ready to pass away. His swim bladder has completely failed him, he can no longer swim straight or stay bouyant. He's been laying on his side all day. I hate seeing them suffer at the very end. I don't have the means to put him down humanely, and I'm sorry, but I don't think I have it in me to crush his head X(. This is definitely the worst part of betta keeping. I wish we had an aquatic vet around here, or atleast some easy access to clove oil. But the poor guy is still fighting, he just won't give up. It's amazing how these little guys keep struggling on even when all hope is lost. I'm just hoping he passes quickly, I'd hate to see the little guy stay like this for much longer
