Thanks. It is a Oceanic 76 gallon half circle. No coral nipping out of that CBB, been put to the test with all kinds of tempting stuff. Loves aiptasia! As for other fish, lost a few recently and never even found their remains. 2 anthias (sunburst and borbonius), rabbitfish, and a couple of wrasses just disappeared. Have to wonder what disposed of them. Still have the CBB, vanuata wrasse, solorensis, 6 line, and 3 pajama cardinals. Will add more fish soon, but want to do a few more changes first, such as adding sand and rearranging the rockwork one last time.
The back glass was covered with coralline, loving the clean look now. Never again will I crowd a tank with too much lr, thus making parts of the glass difficult to clean.
