angels becoming intolerant of each other

[triazole]

tank - 29g. mated pair of angels, though they have failed to hatch the eggs, and have eaten them everytime they spawn. recently they are really starting to hate each other. here's a video that i took -

my angels do that all the time, as far as i know that is normal sparing. as long as they are not causing physical harm to each other i would not be worried

i believe its mostly for show. there hasn't been any missing scales or frayed fins. so, i'll just let them be. they've cleaning a leaf for quite some time now. so i'm guessing more spawning is on the way.
