Trust me, I have seen much nicer tanks (mine looks more like a science experiment than a display tank!). It does look pretty good, but I am thinking of redoing the rock work in a more open manner. It kind of looks like a pile of rocks in a quarry right now, just more colorful.
I went to 14K XMs which really gives it a deeper water look, which makes the zoas colors really stand out, but they don't grow as fast as under 10Ks, and my blue ricordea really dulled in color under the 14Ks. They actually looked a deeper blue under 10Ks, which doesn't make sense.
