Dispar Anthias acting strange

[stan450z]

Pic attached. Have 3 dispar Anthias. Known to be schooling fish... but mine have been anything but. I have one that swims all over the tank and the other two sit motionless in each opposite corner of the tank wide in the open. They all eat fine and swim together while feeding. So strange. Had them for over a month. Acted like this as long as I've had them.

any other stock in the tank may be bullying that would be my guess,

I know I've had a very tough time adding new guys into my tank!

Kole tang - swims like nuts (had tangs before but this one is crazy!), ocelaris angel - a bit agressive sometimes but mostly peaceful (he also does that strange thing hanging out by my powerhead in the corner - heard these clownfish are notorious for that), a blue and yellow tailed damsel (8 years old!! And original tank member - peaceful as can be) and the 3 dispar Anthias.
