Ahh, well since he is still new... Some take a lot longer to adjust. I recommend perhaps for a couple days, don't use the light. Transition to a light being near him, then eventually have the light on with something on the surface to block half or most of the light.
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
