There are more instances of connections between Aedra and Daedra than there are instances of clear mutual hostility. Peryite and Akatosh apparently are connected somehow, probably because Peryite really is a dragon rather than just pretending to be one as some people seem to think. Oddly, the followers of Stendarr and Boethiah sometimes work together, probably because they have a mutual enemy in Molag Bal.

Speaking of Molag Bal, the one instance of clear mutual hostility I can think of is the antagonism between Molag Bal and Arkay. Supposedly, Molag Bal created the first vampire specifically to spite Arkay and mess with the mortal cycle of life and death.

Much more common are rivalries among the Daedra. Daedric politics is infamously convoluted, especially to mortals. For example, Azura and Molag Bal have been reported to be "allies", even though they are almost perfect opposites. I think this is definitely a case of "the enemy of my enemy is my friend" and they hate everything the other stands for. But being opposites probably gives them an advantage in being able to understand one another, which probably means that they have a hard time deceiving each other too and therefore make good "allies" against mutual fiends. Makes sense in god-logic, but again seems convoluted to us mortals.
