But in the topic of a blue fish for your future, I would recommend a chalk bass. Really fast and cool fish, one of my favorites.
Yaa the yellow tang is definitly a huge problem, and im happy you said that. Honestly, i was just relieved when i realized the OP didnt consider blue tang for her "blue" fish. Lol
I agree with the chalk bass comment!!!
