first you need to do a fishless cycle in it before you put any fish in it so the good bacteria which breaks down fish waste can grow in the filter and cope with the fish's waste load, otherwise the fish poo which creates ammonia will just build up and kill them.
Thats not 100% true. I know loads of people who have done cycles with fish sucessfuly. I did all my tanks on it.
Its really just a matter of taste, and time. Its different for everybody.
Sorry if this was alittle off topic, I just hate people saying fishless cycle is the only way to go, and if you do it another way, you will fail. When people ask me, I always suggest to them the cycle with fish first. I think itrs more exciting for begguiners, becauswe they dont have empty tanks just sitting there filled with water. They might lose intrest before they actully get fish.
Just my 2 cents.
