I rarely him gasping at the surface for air, even in the morning.

I think he got plenty of O2 during the day when plant photosynthesized. At night, I run an airstone just in case O2 run out.

If the goldfish always gasp for air, I would say it related to swim bladder disease, where it is difficult for them to swim down.
