So i am right now in the process of fishless cycling and I took a look a closer look at the rocks in my tank and saw that some of them are kind of rough while some are smooth. In order to save money from buying gravel I bought 75lb of Home Depot rocks (each rock is about 1 inch to 1 inch and a half). I cleaned these rocks with water very thoroughly. My question here is should my fish be safe from rough rocks once i put fish in or should i buy a bag of pet store gravel to create a thin surface above the rocks?
