Final update:
I went on vacation and unfortunately there was a temp swing and my clam died. Also my bf didn't feed the same way as I did (I made sure the twin spot always got something to eat) and the twin spot died. Other than that the tank looked great when I got home and the anemones are getting big! Almost 5" across now.
But we've decided we need to cut back on somethings and are taking down all our tanks, except for our 150 gallon. So the cube is acting as a frag tank now and once all the frags are sold, we'll be selling the tank too.
It was nice while it lasted.
