My friend's formerly healthy, young male betta is exhibiting some symptoms and we're not sure exactly what's wrong with him.
He ballooned up a little towards his front end and this ballooning is translucent. He seems to be having difficulty swimming, though he is not lying on his side as in the swim bladder description. His temperment has changed drastically - he went from being calm and happy to being very nervous and jumpy. He doesn't seem to be constipated. I've tried fasting but to no avail. The water is changed weekly and a de-chlorinator is used.
Any ideas as to what's going on?
