You have some really nice looking colonies in there. Tank looks great. What fish do you have in there?
Most of them are pretty small fish so as long as your tank can handle the bioload i can't see how any of them would be that unhappy. Do your scooter blennies eat prepaired foods? I like them a lot but have always stayed away because they can be so picky.
Also I am running a octopus skimmer nw150 which is more than enough to carry the Hugh bio-load that I have and I love to feed heavy....
