The rule is 1 inch of fish needs at least 1 gallon of water. A tank usually has an inch or two of gravel at the bottom and is usually filled to within an inch of the top so if the tank is 12 inches deep approximately one quarter of it is not holding water. Now in your case you would be lucky if your 15 gallon tank is holding 12 gallons. So doing the simple addition it looks as if you could have up to 12 inches of fish in there. So any combination will make it up ie 1 x 12 inch fish, 2 x 6 inch fish, all the way down/up to 12 x 1 inch fish.

Also, you must look at the needs of the fish you wish to add and the available territories and temperaments of the fish. Since you could fit easily 25 damsels in there, 25 tangs would not work as they get much lager and require more swimming room.
