So I decided to cover it up.
I put down a very thin layer of Carib Sea crushed coral (just enough to cover most of the bottom). I left the back part of the tank BB.
I couldn't use sand as there is too much flow. Anyway she's happy now. I liked the BB: very easy to keep clean. This looks better though. If I decide to go back to BB there's not much to remove.
And my new acquisitions:
Lamarck's Angel ( she's about 3.5" long and a very pretty silvery blue colour)
I also got a bunch of assorted snails, a few peppermint shrimp and a frogspawn coral. The shrimp are relegated to the sump as the Hawkfish might eat them; and the Harlequin Tusk (on order) definitely will. Also have a Chocolate Tang coming soon. When the Chocolate tang gets here and after QT, I will put it and the SF tang (from the 90 gal) in at the same time to avoid any conflict.
