I actually wonder if your flame hawk had something to do with it. Maybe the clown defended its eggs against the flamehawk and lost the battle.Thanks for checking i. Left in the sump for almost a week and he did not change his behavior. would not swim correctly and almost seemed half brain dead or malfunctioning to a sort so I had to put him out of his misery unfortunately. Such a strange event. my thought is that the female hurt him (head butt??) for some reason. Going to get another clown fish today so she has a new partner.
