Most people these days are doing a fishless cycle, and Its rather important.
I'm sure someone can provide a link to the fishless cycle, i'm afraid I don't know it.
But it will require you testing your water every 12-24 hours, for a few weeks-months even.
It sounds daunting, but its best for your fish this way.
The other way is fish IN cycling, less approved of these days, as it can cause damage to your fish..
So, it all comes down to, are you patient enough to give your fish the best they can get, or are you going to dive straight in and be prepared for the possibilities of causing a couple fish deaths, horrid yes, but nonetheless a reality.
Whatever the choice, the lovely users here will guide you all the way through your cycle, and everything will be lovely!!
