I would consider getting a bigger tank, I've upgraded my skipper's tank twice now, and they're happy in their newest one (I've had them for about 1 1/2 years now).
The best place to do this, is garage sales! You can get 15-50 gallons for 20-100 bucks.
One other option is to increase the number of hiding places. Can they both bask without seeing each other? Is there room for one to eat where the other can't see? The pack mentality of skipper's is usually the dominant one pigs out, but makes sure the others don't starve. That way he grows faster, stronger, and larger and can maintain the hierarchy.
