I have a little trouble with my photoperiod, being that it's on longer than the sun is up. Once the house gets dark and he sees his reflection, he starts to act aggressive, biting and flaring at himself. He even spooks himself and shoots across the tank like a flight reflex, this seems to be the real problem there, I hope he doesn't scare himself out of the tank or his own skin one day. I've since moved the photoperiod back an hour to only subject him to about an hour of this while leaving us some time to enjoy the tank in the evening. We make sure to turn the room lamps on to diffuse some of the reflection. Plant cover helps a lot but this particular scape obviously makes it impossible to hide the glass or block his reflection. The black background makes it worse.
