Okay, I'm thinking it makes sense to move the Foxfire Tail column from Dragon Abilities by Age to a separate table in the combat entry.
Furthermore, I'm thinking 1d8 would work better for the tail touch foxfire damage than 1d6 if we wanted it to do roughly the same damage with both attacks. If we'd rather have the touch do less damage with vastly better accuracy I'm OK leaving it as-is.
Thus:
Foxfire Tail (Ex): All hu lung dragons can make melee and touch attacks with their tails that can inflict foxfire damage. The dragon usually makes a tail attack as a primary natural weapon attack and makes its other natural weapon attacks (bite, claws) as secondary attacks, but it does have the option to make a primary attack with its bite and a secondary attack with its tail.
A hu lung dragon has increased Reach with its tail. Consult the Foxfire Tail Table for the reach and typical foxfire tail attack damage of standard hu lung dragons in each age category.
Tail Slap: If the dragon hits with a melee attack from its tail, it does bludgeoning damage plus 1d4 foxfire damage per age category of the dragon. A hu lung applies its Strength modifier to its tail slap's bludgeoning damage normally, it does not apply 1.5 times its Strength bonus like a standard true dragons.
Tail Touch: If the dragon hits with a melee touch attack from its tail, it does 1d8 foxfire damage per age category of the dragon. The hu lung does not apply its Strength modifier to its tail touch damage.
