Clownfish charging then swimming up glass

This is the second pair that is doing this and it is getting me really frustrated.

The only thing "abnormal" about my water parameters is the fact that my phosphate is and has always been 0.1 but the clowns have only recently started doing this.

I paired them myself and they haven't spawned yet but are together all the time and charge the glass with one another before swimming frantically up or down the glass and then back to their anemone/corals.

I notice it mostly at night. Is it the reflection and the fact that they are "becoming of age" and therefore more territorial to anything that looks like them, is it the phosphate, or could there possibly be something else wrong?


Any input would be appreciated.
