Update:
My Magnifica is no more. RIP Feb 2010 after in my tank for 19 months.

Its demise could be from several or all of the following reasons:
1) New batch of frozen food fed. No problem with any other inhabitants though.
2) I added a Haddoni that was inflating and deflating that died in the tank
3) I did not clean the overflows because I added baby Percs and didn't want them sucked in, thereby making the suction stronger in one spot, causing a Bubbletip Anemone to be sucked in and chopped up in the tank.
I have re-arranged the rock work and put a RBTA on the left side for the two clowns. Something very interesting happened. The two clowns no long felt they had to or wanted to defend their anemone. They peacefully let baby clowns and their other siblings stay in the RBTA. The female sometimes sleeps on the right side. Sometimes there are 5 clowns peacefully hanging out in the one anemone on the left now.
I took a bunch of pictures to document possible color changes going from a Magnifica to BTA's. I do believe they are taking on some of the muddy colors of their siblings rather than the vibrant yellow and black coloring.
Tank is looking great, I will post new pictures and videos soon. I have a new HD camera.
