Love the tank both now and before!
If it was mine I would add more brigh coloured fish (which you may have but they may be hiding)... I can only see whats in the pic
Looks much better rock scaping wise and lighting wise. However you do need some brighter corals. There are pleny to choose from. Even little frags will eventually fill out so there's no need to "break the bank" on them either. Def look to local clubs for frags
