I would watch them and see. My fuzhonmgensis will grab each other when feeding, but do not bother each other territorially. I f you notice animals being chased and snapped at tround the tank, or fighting occuring outside of feeding times, you definately need to watch out.
If you notice aggression not linked to food, remove the aggressor (unless it is also attemptining to breed with a feamle) as removing the bullied will cause the stress of a new habitat to be added to the stress of bullying.
The best thing to do when feeding aggressive feeders is to cut chunks of lobworm, and offer them to each animal in quick succession. They usually grab each other when one has food and the other doesn't,,so if the all have food in theior mouths it tends to avoid 'jealousy'. If you use small food itmes, such as bloodworm, try putting it in separate piles or spreading it over a wider area (but not so thinly spread as to prevent them finding it) rather than one big pile, and guiding the newts to take different piles/areas. This will only work if the newts are very tame.
If the fights are feeding re;lated, don't bother to split them up unless one animal starts to try to eat the other (eg swallowing the tail) or is causing damage to the other. They usually realise that their tank mate is a bit too big to eat and let go.
Interestingly, I have found that Paramesotriton will be very tame and aggressive feeders in their first setup after being bought from the pet trade, but once they are moved they become very shy and much poorer feeders, relying more on sight than smell, and require a lot of tme and effort to regain their trust.
As I said, keep an eye out for bullying, but don't worry about feeding frenzies.
