Where can I buy flat slate rock suitable for an aquarium?
Really you can get it from anywhere. I live in America, so not to sure how it is over there. But here I know that you can get rocks, stones, slate, and other natural things from the pet stores, but they charge a lot for them. It is a lot easier to go to a landscape supply store and buy it there, it is really the same thing, you may have to clean it first, but that is like anything you buy for you aquariums. Also buying it there will save you a lot of money because people usually want a lot of it apposed to a pet store, people may just want a few pieces for their tanks. Hope this can help you some, like I said I really don’t know much about how it is there, such as prices, and stores. But if you have any questions feel free to e-mail me.
