I had cheato and caulpera in the fuge and it never grew. :-( Just stayed the exact same for the last year or so, still bright green just didn't increase in mass. Plus I had aipastias starting to grow on the rocks and even in the macro so it seemed like an easy way to get rid of it. lol
I like the orange shoulder tang also like the scopas as well. The orange shoulder at least looks nothing like my other tangs, that's another concern with adding an extra tang so late in the game. The scopas might not get along with yellow though, the blue hippo I have looks so unique so that one shouldnt be an issue and the tomini is a wild card. lol So I need to try to find a tang that doesnt resemble those guys in color or form. I've considered the purple but the price tag is a little too steep for me for just one fish. LOL
