If your tank has only been up for five days then you will need to wait a while yet before you think about any corals. Right now you should actually have nothing in the tank but rock sand and water, as those fish will probably take quite a beating with the high ammonia levels that are bound to show up. Your levels are still going to look good because the tank is young, but in a few days you will see a huge ammonia spike and probably have some trace form of nitrites. Once the ammonia goes down, the nitrites should go up for a couple days or so. After that the nitrites drop and the nitrates shoot up. This is where you can start doing small water changes after the nitrates drop and start to plateau somewhere. Using water changes, you should be able to get the nitrate level to 0, then you can add your clean up crew (snails and hermits). After about 2 weeks with the clean up crew doing there job then its time to add fish number one. This is of course assuming you are not quaranteening any new fish (would recommend it but most new to the hobby don't do it). Make sure you go slow or you will end up wasting a lot of money and getting quite aggrivated with the poor success rate. Remember this: Rushing through it will take a lot longer.
