The rough rock section has all kinds of rocks for selection. They charge by the pound and have a good variations of sizes, but it depends on the tank size your working on. I bought Arizona rainbow petrified wood from them and great price for two of my tanks(20L and 12 gallon nano). You should call and make sure they have the rocks in stock your looking for, just my advice.
