Porcupine puffer is afraid of light?

What do you think? My puffer seems to hide from the light all while the lights are turned on, but the minute they are turned off, he jumps out and swims all around the tank? What's up?!? Are the lights too hot? Too bright? They are only on from about 4-9 at night, longer on the weekends. There are two "standard issue" lights that run the length of the 90 gallon tank... He was the perkiest fish in the lfs, and now he is hiding! What gives??

Puffers are nocturnal. Normally my puffer will only come out right before the lights go out, and he'll stay out a short period of time in the morning.
Also if your lights are not on a timer I would suggest putting them on one. As well I would have a regular periond of lighting. Fluctuating the amount of time, and when they come on/go out, can be stressfull for fish.
