I have 2 beautiful betta boys (in separate tanks of course): Draco and Luna.
I've had Draco for almost two years, and I don't know how old he was before I got him from Petco. About a month ago, Draco had a touch of dropsy or something that made his scales protrude only a bit and a smidge of fin rot (I feel so awful about that... I guess the water was dirtier than I thought... it appeared clear and clean to my eyes). I treated him with lifemed and he appeared to improve greatly: his scales went back to normal, and his fin is much better.
However, then he developed swim bladder and it's getting much worse. His colors have changed, he has a protruding belly, and he spends all of his time lying on his side at the top of his tank unless provoked. I fasted him for three days as recommended and for about a day I thought there was an improvement, but now the symptoms are back with him still being fasted.
I'm heartbroken and feel like such a wretched owner, I don't know what to do. Is he in pain? It's so hard to tell... and if he is in pain then I don't want him to suffer: for euthanizing (I would ask my father or my boyfriend to do it... I couldn't bare it) I read in one place that freezing in the fridge is preferable and like going to sleep, but then I read somewhere else that would be a horrible way to die.
What should I do? Please help!
