Not sure what his deal is this last month. Had him for about a year, he was mean to the wrasses at first, then a few months past and I got rid of a starcki damselfish and now he's chasing/flashing/sometimes nipping my other fish. Plus every 10 minutes he's nipping at a coral.

Why is he more aggressive the last two hours before the lights go out?
Frustrated, think it's time to rehome him?
