Basically I'm new to this hobby.

I bought a tank and set it up and everything, but my mistake was listening to the people at the store. I just waited a while before buying fish as i didnt know about fishless cycle or anything like that. So now i have a Glofish living in a small one gallon tank by himself and no idea if he is going to live or not.

What should i do?
How can i go about doing water changes? I have Tetrasafe de-chlorinate so how do i use it to do a water change.

I want to be able to continually do water changes or whatever i need to do to be able to save my fish from death. I know i need to keep the ammonia levels low, HOW can I go about saving him???

The first goldifsh alone needs 15 gallon for a fancy goldfish, 20 gallons for a common goldfish.
They are massive waste producers and need double the filter size to the tank.
I would take him back to the lfs if you can't supply him with a tank he deserves.
You will need to move him into a bucket with his bowl water and then clean the bowl and add fresh declorinated water
to the bowl, you will also need to match the temp of the water.

GloFish...

Sorry I need some specs thought it said goldfish read it wrong.
Don't know anything about glo fish best to post in the right part of the forum,
or tropical discussion.
Good luck.

Glofish are genetically engineered zebra danio strains - other than the color, no different.

All it does is take water changes - as many and as frequently as necessary to keep ammonia and nitrite under 0.25. For such a small tank, even with a small fish, that'll probably mean changing half of it at least once or twice a day.

don't feel bad, alot of 'serious' fishkeepers started out with bad advice...
get 2, gallon jugs so you always have a ready one on hand, fill them each with water let them get to room temp, add the right amount of declorinator...dump the old water, add the new ... see if you can get at least a 10 gal tank to move him too, and start a fishless cycle, with a 10, once it's cycled you add several more fish...don't over feed that guy,see if you can get one of those tank vacs, or at least a the tubing to siphon the water, it's so much easier then scooping it out or dumping it out..cus you dont have to move the fish they're are alot of good web sites and forums where you can read up on fish keeping common situations ... etc PM me if you have any questions, ps when in doubt, do a a water change, oh and get a little 'aquarium salt' that will protect the gills if the ammonia level rises...with daily water change you shouldn't have to worry too much there's actually several more suggestions I have depending upon what you decide to do about the 'tank'

Definitely get a larger tank. Even though danios/glofish are small, they need large tanks b/c they're very active.
I would do as eb2 suggested and get a larger tank and start up a fishless cycle. Keep doing daily water changes in the 1 gal tank. I'd get some Prime to help neutralize the ammonia. Maybe something to put in to the filter (if the tank has one) that absorbs ammonia.
But keep up with those water changes.
Go out and get yourself a liquid test kit that tests for ammonia, nitrite, nitrate, ph etc etc so you can keep track of your fishless cycle.
And just hope that all that effort helps keep the lil fish alive.
Once the tank is done cycling, do a large water change (90%) and put him in after acclimating him. Then go out quickly and get yourself some more. Danios do best when they have some buddies (minimim of 5-6)
