What tank size would I need?(For future reference)

[travie]

What would the minimum tank size needed to stock a Blue Tang and a Yellow Tang in the same tank along with a few(also how many could the few be?) other assorted fish that stay around 3 to 5 inches? I know I would have to factor in aggression into the other fish.:14:

I'm asking for future reference and hopefully to get the significant other to stop asking. Thanks for the insight.

blue as in blue hippo or powder blue? IMO for a blue hippo, yellow, and a few other fish youre looking at a minimum 220g, but better a 280g

[unleashed]

I agree with cocoa. You may be able to house them in a 180g, but after about 6 months or so, a 220g to 280g is best
