Can't tell by the pic but it looks pretty caved in. If it was a classic or vintage bike and you were trying to "keep in orginal", I would cut out the side and weld on a new piece. Hammering and bondo... not sure about that approach, looks too far gone for that.
In this case the best way to go would be to hunt around for a tank on line, see if you could score a uesd one and have it painted to match. Buying a new one - second choice.
