If it hasn't got a filter you are limited to the type of fish that will live happily in your aquarium. In any case, use prime in the water to dechlorinate it and neutralise nitrate and nitrite.
Without a fliter, you wont have your fish for long and will need to do daily water changes.
fish do not die in filtered water instead they will de if there is no filtered water try ussing one of the fluval brands for the size of your tank. maybe you did not cycle the tank before you add fish. how big is your tank and what fish o you keep?
Yes! You should never use chemicals to clean your tank, especially while there are fish in it.
Yes, if you wash it out before you reuse it.
Not in its self. The fish could jump out of the tank and land outside the tank, though.
a fish
if you have a tropical fish or a filtered tank than yes you do need a light
get a 5+ gallon heated and filtered tank
Betta fish will not be harmed if they are in a filtered tank. If the new tank is about the same size as the old tank you should use the old water or most of it in the new tank. If the new tank is larger so you have to add lots of new water then you should fill the new tank with the new water and let it sit (preferably with the filter running) for two or three days before adding the fish. Also when you move the fish make sure the new tank is at the same temperature as the old tank.

Wash it thoroughly in water & detergent, to get rid of any possible residues - then rinse it well before introducing it into the tank.
You should have it running for about 2-3 days before putting fish in your tank.
Dechlorinated tap water (aka freshwater). Make sure the tank is well filtered and fully cycled, and a suitable huge size for Goldfish, before the fish is bought and introduced!
I filtered mt plant.(simple one) I filtered my fishes tank.
The dragon fish breaths in air from the water so keep the tank well filtered, or have air bubbles.
A big fish tank is as long as its been built. 'Big' is a subjective term. Ask yourself, how long is a big fish tank, to me? That is where your answer lies. For me, a 'big' fish tank is anything over at or over 4 feet long.
Of course you can.
I would wait a little longer... but it might work that is up to you however the fish might die quickly if you have not put all the nessesary chemicals in the tank of if the water has not been filtered enough times
