Your fish can be put straight back in the tank after using dechlorinator, as long as you have not performed a whole water change. A 30% water change every 2 weeks is recommended, and putting your fish back in the tank straight after this change of dechlorinated water shouldn't do them any harm, just as it hasn't done any harm to my 3 healthy barbs (1 rosy, 2 odessas.
No; chlorine damages and destroys the gill tissue, which will cause your fish to die of suffocation.
There are a number of things in water that make a fish live such as oxygen, sources of food, and many minerals.Contrary to belief, fluorine (fluoride) in tap water does not extend the life of a fish, and this is why fish keepers use water conditioner (dechlorinator) during each water change.
the only time you need to use a dechlorinator is when you do any water changes. you always add dechlorinator to any new water goin into the tank. once the water is neutralized you wont have to add any more. just make sure to follow the directions of the product you use.
It will be stress to your fish and even it can be dead. So do not, I repeat, DO NOT OVER DOSE!
That would be nice. Especially if your town uses a lot of chlorine. Letting water stand for a while it out gasses a lot of O2 and some chlorine gas as it rises to room temp but it may not be enough. A dechlorinator would be helpful.
It's not recommended because it's usually too hard. Tap water with dechlorinator added to it is the best way to go.
Give it good food and don't miss feeding it! if it is infected by other fish than move it away from them but if it's a sickness, then add dechlorinator 2 teaspoons in a jug with water, mix it well, and then put it in your aquarium.
No. Chlorine will break down on its own...eventually....but it will take days and days. (And your fish would be dead by then.) If you have a fish tank, you need to buy a bottle of dechlorinator - it is not expensive.

fish breathe by gulping water , using air in it.
No. Distilled water is completely devoid of the essential minerals fish need for long term health. That's what the distilling process does, it makes the water pure. Mains tap water is usually perfectly fine for fish provided it's got dechlorinator in it (to remove harmful chlorine/chloramine and heavy metals). Also, they're called Siamese Fighting Fish, not Japanese, they originate from Thailand, old Siam, not Japan! But it's more professional to call them Bettas!
if u don't have enough water conditioner/dechlorinator in the water it is very common that the water will kill the fish and soo i would not recommend putting the fish in without a little more conditioner it wont hurt the fish if its just a little extra. but always remember to aclamate the fish and by the time its done(20 minutes or so) the ice should be melted be sure the water isn't too cold or too hot if u can just buy a tank thermomiter with a green area between the tempatures most fish need. i hope i helped :)
