Porcupine puffer feeding habits

[eigo]

I have had this porcupine puffer for about 2-3 months now. i have a 300 gallon aquarium with a dog face puffer, blue tang, purple tang,emperor angel, flame angel and the porcupine puffer. My problem is that my porcupine puffer usually hides within the live rock during light periods and then is very active during the night period. i know this is normal since the porcupine puffer is are nocturnal but i was looking at some videos on youtube in the past and they are very active during day periods. how can make my porcupine puffer more active during the day light periods?

Interesting question...I wonder if you could do it like you get a baby on to a regular sleeping schedule......Slowly change the time the lights are left on to later and later....?

Is it possible the "daytime fish" are harassing him during the day?
