Hello everyone. I've come to this site many times before to find information, but this is my first time posting here. I'm hoping I can get some more advice and some second opinions. First off, here is some information:
Housing
What size is your tank? 1 Gallon Tupperware
What temperature is your tank? 78 Degrees F.
Does your tank have a filter? No
Does your tank have an air stone or other type of aeration? No
Is your tank heated? Yes
What tank mates does your betta fish live with? None
Food
What type of food do you feed your betta fish? A mix of tropical fish flakes, betta pellets, and sometimes freeze-dried worms.
How often do you feed your betta fish? Once a day, with freeze-dried worms being a treat every few days.
Maintenance
How often do you perform a water change? NA
What percentage of the water do you change when you perform a water change? NA
What type of additives do you add to the water when you perform a water change? When I do water changes, I add Tetra Aqua Safe "Dechlorinates and conditions".
Water Parameters:
Have you tested your water? If so, what are the following parameters?
Ammonia: NA
Nitrite: NA
Nitrate: NA
pH: NA
Hardness: NA
Alkalinity: NA
Symptoms and Treatment
How has your betta fish's appearance changed? No major change. Some fuzz is still on him.
How has your betta fish's behavior changed? A little shocked, you could say, but swimming around still.
When did you start noticing the symptoms? A few hours ago.
Have you started treating your fish? If so, how? Yes. I have him in a quarantined one gallon Tupperware bowl with a small heater, heated to 78 degrees. I did a 100% water change and added one teaspoon of aquarium salt (dissolved and mixed with the rest of his water). He has a plastic plant in with him, and he is covered with a lid and a towel.
Does your fish have any history of being ill? He has some minor fin rot.
How old is your fish (approximately)? Maybe three to four months.
Here's some more background information, not extremely pertinent, but hopefully helpful: I got my original betta, Nix, about three months ago. This is about the time that my friend got his betta, Hans. About a week ago, my friend said that he wasn't able to take the best care of his betta (he wasn't able to do water changes very often, and he only got fed once every few days or so) so he offered for me to take him. I took him, and after arranging some things, put him in a ten gallon divided tank with my original betta, Nix. They were working out fine until I filled the tank a little too high and they could see each other through a small hole in the divider. After a day or so of flaring, I decided that I would move Hans back to his one gallon bowl so they wouldn't cause too much stress on each other.
The Incident: After I had moved Hans back to his bowl, I had foolishly forgot to cover it back up. I can't be sure how long he was out of the water (maybe up to three hours) and I'm can't be sure if he was even still moist when I found him, but I had found him under my desk covered in quite a lot of fuzz from the carpet. In my panic, I went to grab him with my hands, and he flopped a bit. I decided to get his net and a small bowl to scoop him into so I wouldn't mess with his slime coat any more. I put him back in the one gallon bowl immediately and he started swimming a bit, but seemed like he was shocked. Kind of still and only moving if he had to. After this, I made some fresh water and added a teaspoon of dissolved aquarium salt to it and then added some water conditioner. I slowly introduced Hans to the new mix of water (which was slightly warmer than the tank water at the time) and now he is in his one gallon Tupperware tub with a heater, his small plant, and a towel covering the entire thing.
I'm sorry this was so long. I wanted to make sure to provide as much detail as possible. I guess my questions are, what else can I do, if anything? Is him reacting to my touch when I went to pick him up a good sign? Is it a good sign that he was moving around when he got into the Tupperware bowl? Finally, is one teaspoon of aquarium salt per gallon of water far too much for this situation? I feel horrible that I took this betta into my care and I had let him jump out of the tank. His previous owner said that he didn't care too much about the fish, and whatever happened would happen, but I want to help Hans as much as I can. Thanks for all the help, and thanks for taking your time to read this massive wall of text. If you need any more information, feel free to ask.
