I personally wouldn't do a sorority in less than a 20 gallon, but I also don't have a sorority, so I'm not saying that from experience. You could divide it down the middle and put a girl on either side, or you could just put one fish in it (my 10 is home to just 1 fish, and some plants) and perhaps some snails or shrimps.
Substrate is all of a matter of preference and what you want to use it for - for example, there are plant specific substrates, or you can use plain aquarium gravel, or sand. Or, you can use pool filter sand, which is chemically inert and just the perfect grain size, IMO. Only problem is, it only comes in white :/
