No, not quite. Set your tank up, and get a piece of raw or cooked shrimp (doesn't matter). You can also just use fish food, but the shrimp may go a bit faster. Put it in a small net or piece of pantyhose. You don't have to do this, but it will keep it in one place, as it starts to decay. As soon as you get a reading for ammonia (first part in the cycling process) you can take it out. Keep checking your water parameters for nitrites, which is very harmful to fish (so is ammonia) and once you have 0 nitrites (second part of the cycling process) you can add fish. Cycling can take 4-8 weeks, but I've usually had it done in 4 weeks. Add fish you want slowly, don't get all of them at once. You want to be careful about creating a bio-load (waste) that your newly founded good bacteria can process adequately. If you don't overfeed, you should be good to go, without getting another ammonia spike. There is lots of good information on this site, about doing a fishless cycle. It's totally the way to go. This prevents you from buying "hardy" fish that may withstand the cycling process, only to than have fish you don't want once you're done. No fish are harmed in this process
You can do a 30-50% water change before you add fish, after you are done cycling. Have fun and good luck!
