    Just in the office, I saw a colleague pour some bottled water into her fish tank. I know she did this for convenience, but can we really do that? Fish can live in it?

Why shouldn't it, what other water then?
I'm currently staying in a Country where the tap water under national standards is higher than any standard for bottled water worldwide.
(Which is only under international standards for the sake of level playing field for foreign competitors in the market for bottled/mineral water.
I even get mineral water directly from my taps at a higher quality standard than can be safeguarded for bottled water.
But I still like the taste of some San Pellegrino at times, so why not waste money on lower standard bottled water sometimes?

Now COnsider this: There are also some fish tanks around here,
what do you guess they're filled with, if not with drinking water.
Where from? THere ain't even much air pollution around to pollute rain water,
-i n this actually quite highly industrialised Region.

If it's a tank with sweet water fish, no problem.
If it's salt water fish, one small bottle can hardly mess up the salt level of the whole tank, can it?
Just check the level and if something's not right, just do what's necessary to fix it.:)

Well, I think there is some misunderstanding here...What I meant by "Fish can live in it?" is that I thought in bottled water there might lack some minerals or oxygen needed for its living...

If your friend's tank is just the type of tank you put on a desk (small), then there is no problem since the oberture on the top already provides the needed oxigen for the fish. The life span of a fish in those conditions is slightly less than in a filter controlled tank because the fish produce a lot of contaminants thru their guills.
If it is a filter controlled tank, one bottle of water will make no difference either since it mixes with the existing water. What you should advise your friend is not to pour a bottle of water where the temperature of the water contained in the bottle is very different from the temperature existing in the tank. That is, the temperature should be similar (for the common gold fish between 19-20 to 22-24 degrees centigrade).

Hers is a small tank without a filter, and that's why she has to change the water every day. If oxygen is no problem, what about the minerals?
P.S. Why the temperature should be similar in the later case, what will happen if not?

I am going to guess she keeps goldfish, which are the most common to be kept in those small home or office tanks. OK here:

Depending of the number of fish she has inside (people keep normally 1 or 2) the water conditions don't need to be too specific for that since these type of fish can live almost in any environment. You can take a walk in some parks and you will them happily swimming in waters far more contaminated than the fish tank. Bottled mineral water, in a sense, is better for a non-filter tank since the tap water has been treated with a lot of chemicals to make it "home usable" and thus not having a filter means that job (to filter) has to be done by the fish.
As for the temperature; fish are very sensible to temperature changes (big changes I mean). Too cold is bad for them as well as too hot. The fish keeps a very stable body temperature and any sudden change can bring it a lot of problems (loss of scales or the called "fish dandruff). It can even cause the death of the fish in extreme cases!
