Blue Streaked /velvet damsel

[krschulz]

I bought one of these awhile back and am now finding alot of trouble keeping my soft corals alive (with good water quality). Has anyone had a problem with this particular species? I know they can be territorial and aggressive but is that toward their own kind or everything else in my reef tank? Have lost frog spawn, torch, hammer corals, gonoporas and the like. Should I segregate this guy?
