I want to do a black substrate for my new 10 gallon tank, but my question is: I want something fine grained (not gravel) like sand or dirt. Is there a black sand that is easily accessible, and would dirt be safe for an aquarium, and if so, what kind?
I've been thinking freshwater, but may try brackish, so a substrate that will work with these.
Will probably be filled with some sort of crustacean.
