Tank Cycling

I've had my tank running for a long time with just liverock, snails and blue hermits. When I first put my liverock in the tank started to cycle then cleared up. My question is when I go to add a fish will the tank cycle again or did it already happen with the liverock?

 

It already happened with the live rock. If you add too many fish too fast, well than it might cycle again, because the bacteria would need to multiply to catch up to waste needs. However, if you just go slow then you will be fine and not have another cycle.

 

Thanks
