Welcome to the hobby, no need to panic.
nitrogen cycle could be started with the liverocks that you added, you don't need a fish of ghost feeding to do it but it will be faster. A fish to start a nitrogen cycle is considered a torture.
The best way is to add a bacteria as everyone is saying. I heard that One & Only Nitrifying Bacteria by Dr. Tims aquatics...
Just watch your fish for any sign of white spots, stress or disease and everything will be fine.
