i noticed that my ps dont liek bright lights, unless i leave it on for a few days, then they start coming out and acting normal. once i turn it out then they act crazy. so i took thins in mind and i mixed the ideas. i flips my flouresent light upside down to face the ceiling. my p's love it. they sleep like this, eat liek this, mark territory like this, act happy and the most normal ive eveer seen them like this. i think i found the best way to light my room and my P tank. i wa wondering if anyone has tried this also, and if not im asking you to, and post your responses. ill bump this throught out the week.
