I finally decided to rehome my PG. Ever since I added him to my tank with platies, cories, and harlequins, he's been traumatizing all of them. I've lost a total of six rasboras, a platy, and a cory. I thought it might be some disease, but they died one by one. Since PG is gone community is schooling again and tank seems much happier. I will update if I'm wrong but I just wanted to shout out to others that think all PG's are peaceful.
