Great stuff, you obviously have a healthy system running there.
Never fool yourself, thinking a breeding pair makes a system healthy.
Banggais, clowns and damsels are not fuzzy.
If mandarins and/or angels spawning, then your system is healthy.
I got a pair damsels in my growout system, which spawns on a weekly basis.
My growout system is far from healthy.
60mg/l nitrate, only room light and a flower pot in the tank.
Very good food and the damsels are happy.
