6-line aggression question

[fishoholic]

Grizz the cleaner wrasse was twice the size of the 6-line, but that didn't seem to bother him.

Myka I know 6-lines can be evil but I've always really liked the looks of them and I have always kept them without issues in the past. I thought because it was in a 230g tank, that that was why the 6-line never picked on anyone in the past, but maybe it was more because he was usually the last wrasse added to the tank. I never saw him pick on the last cleaner (however he was added before the 6-line) so I didn't think it would be a problem, obviously I was wrong.

Unfortunately I just checked on the cleaner and I found him dead, not to surprising considering the amount of injuries he had, but sucks knowing one of my other fish was the cause of his death
