Tank is very stable. Its about 150 gallons total volume w/ ATO, cal reactor, carbon, etc.
It also houses about every coral you can think of, acros, montis, chalice, acans, micros, favias, xenia, cespitularia, duncans, tubastrea, welsophyllia, symphilia wilsoni, euphyllia, calulastrea
The light covers half of the tank so it can choose between direct or ambient light.
I am a little concerned that it wandered behind some rocks
Its an awesome specimen though and Id hate to loose it...
