Oh doh! It, the FTS, totally slipped my mind.
As for the yellow tangs, or any tang, it seems the secret is food. They thrive on more rather than less, in my experience. I would attribute a bunch of my success to auto feeders and regular feedings.
Your tank sounds so fun! I would love to follow along if you have a journal.
I may have found my next QT inhabitants.
In other news I am super unhappy with my black tang. The thing hides ALL the time. Boo! Barely comes out to be seen. He may be out more often in the dawn/dusk and night hours but he's hard to see.
