New Fish - Orange Shoulder Tang

I added an Orange Shoulder Tang to the tank.  He's a fair size, roughly 10", which is good since my Hawaiian Blue Hippo Tang, roughly 8", can be initially aggressive to new fish.  He did try to bully him at first, but the Orange Shoulder Tang wasn't having it and quickly put him in his place.

This makes the Orange Shoulder Tang currently the biggest fish in the system and is the new "King" of the tank.  He's quite well tempered, and I sometimes find him "keeping peace" amongst other fish, whenever aggression breaks out.

Tank Access From The Den

I decided to open up the tank from the Den.  It's difficult to perform tank maintenance, as well as aquascaping the view from the Den.  This should resolve these issues.

I cut out the gyprock, framed it with wood, and attached it using a hinge.

New Metal Halide Bulbs

I needed new Metal Halide bulbs and decided to change to the Reeflux 250w 20000K SE bulbs.  I've heard a lot of good things with this bulb.  Most 20000K bulbs are too "blue" and dark, however, this bulb looks closer to a 14000K bulb.  As well, it has more par than its 12000K counterpart.
