Will new lights stress fish?

[Baffels]

Its me again!

Just turned on my lights today as I got my first set of corals yesterday. They are A360Xs and are on acclimation mode. I noticed this afternoon that my two clowns were "chasing the glass" and then hiding in the back, not their normal spot. The foxface and two cardinals seem unaffected. Ammonia/nitrite 0ppm, nitrate <10ppm.

Would the lights have this effect? Or is something else stressing them?

Sudden changes can in light can spook them. Was this pretty much right after you set the lights up?
