Since you already have an ammonia producer in the tank (i.e. liverock), you do not need to add anything else to start the cycle. Also, it is no longer reccommended to cycle using fish as it is very stressful on them. The preferred method of cycling a tank is using liverock and a raw shrimp from the store. Chuck the raw shrimp in the tank for a day or two until it starts to decompose and kick off the cycle. Then take out the shrimp and discard it far far away as it is not a pleasant smell.
