i have heard that lungfish can be very aggressive and terretorial, even to each other. The larger and/or stronger one might be harassing the other one.
However they could still be stressed and getting used to their new home. I suggest providing a couple of hiding spaces to make them feel more comfortable and reduce any possible aggression.
BTW welcome to MFK
