Hey fishman...Just want to let you know..that My experience with the cherub was not that great..He was a beautiful fish, and very entertaining..for awhile..never had any probs with corals...but he was way too aggressive for the other fish..chased several of them til they finally jumped out..I blame him for the loss of my 6 line wrasse, my fairy wrasse, and my jawfish, before he made the trip back to the LFS...after what seemed like years,(LOL), of trying to catch him...just letting you know of my experience...good luck..And I would buy uncured rock...the exta life you will end up getting is well worth it..too me, anyway..All the rock I have, 150lbs., was uncured and alot of it was florida rock, and never got a bad hitchhiker...anyway ..goodluck, sounds like you are on top of it....My only other suggestion would be..start planning room for the 55 or the 75 or the 125, whatever is next...This is a "BAD" habit...just ask my wife....LOL
