So... 3 days ago I posted another thread here saying that my fish was a little bloated with slightly raised scales. He was still swimming around without any problem but wasn't eating a lot. I kept him in clean and warm water just as you guys told me and to fast him a little to help the bloat go away because I had no idea what to do, yesterday he seemed to be doing a little better and he had built a small bubble nest.
So when I woke up this morning I ran to my tank, opened the light and there he was, floating on his side, lifeless.
I started crying because Admiral Apocalypse was my favorite betta, I've had him for a year and he had never been sick and in 4 days... BAM, dead.
I you have any idea what could have caused it, I would appreciate your input, I'm not having a very nice morning but I'd like to know what could have caused this. I don't feel bad about what I did... I feel like I did what I could to save him but damn this is sudden....
Thanks to everytone who commented on my other thread and tried to help me, again I appreciate it.
