This is the second betta fish I've had in two months and I think I killed him. I was treating him for minor finrot by keeping him in 1 gallon with daily water changes, added aquarium salt and kept the temperature at 82*. He was improving, finrot just about went away. Well, I read that frozen bloodworms are good to feed them so I broke off a little piece of the hikari frozen bloodworms and defrosted it in water treated with dechlorinator.
Not too long after giving him the bloodworms his health went from good to bad. After feeding him the bloodworms I fasted him for a day. It didn't appear that he was overfed, he swam normally. After fasting day, I fed him 2 pellets and he didn't even eat them. Then I noticed that he was gasping for air and swimming to the top gasping for air. So I immediately put him in a cup and floated it so he would stay warm. I watched his final moments, it looked like he was convulsing.
I think this is what may have happened to my previous betta too. I didn't think it would be a problem to feed a small sliver of a cube of frozen bloodworms, but perhaps I overfed them. What is the proper way to feed frozen bloodworms to a betta? I really thought that wasn't a lot of food but maybe I'm wrong? Or is it possible that there is something wrong with the bloodworms, could they be poisoned????
I feel really horrible.
