For those of who know about my most recent betta who wasn't doing well... he died the other day . I had one die on me not too long ago as well. I couldn't figure out what was happening. I buy the fish, find out it has fin rot and start treating it, I put them in a small goldfishbowl and they both had the same kind of problems that lead to death. I thought that it was the fact that I had added water and "betta fix" to my bowl? I emailed the company who made the "betta fix", to ask if its ok to mix with salt, more than six times on 3 different email accounts and still no reply!! But I think that I have found the answer. There must be some kind of chemical in my fishbowl. Back when I first baught the bowl and a small goldfish I don't think he lasted very long in it. I have become very frustrated with keeping bettas because of this bowl and I would like to try another, but im not sure when or if I will at all?
