Can you have bottom dwellers with a black sand substrate?

[Raja Jago]

Well, I heard this insane theory the other day about how you can't have any kind of black sand in your aquarium ( Flourite bacl, Tahitan Moon Sand) with bottom dwellers. People have said it contains sand with sharper edges and can be harmful to any bottom dweller ( Pleco. Otto, Cory catfish). Is this true, I have heard many people say it is fine, and they do it, and then I hear people say don't because it might hurt them. Can anyone tell me the truth, I think it isn't true but still won't to know what other people think...

My fish are fine with it been over a year now. I have heard that but only when referring to blasting sand.

Color is not important, however type of sand might be. black granite sand will have similar properties to white granite, or any other color for that matter (granite grinds smooth, that's why Indians didn't use it for arrowheads). However something like obsidian might very well be a bad choice. In closing, color not important, material/mineral, might be.
