I'm trying to decide on what kind of stone I should use in my 100 gallon american cichlid tank that I am setting up. I decided I wanted to do dragonstone because it looks so cool but I noticed it has sharp edges. I don't want to hurt the fish. Would dragonstone be okay in my american cichlid tank? If not any suggestions on other rocks I could use that would look cool and maybe provide good hiding spots for the fish.
