265 gallon setup

[niloc16]

i know the tang police will probably freak out on me but this is why i am asking to get peoples input. i have a list of tangs i'm really looking at getting for this 265 and i'm wondering if the stocking is too many or if they will get along together in the system. remember i'm not planning on doing the typical wall of rock but doing a lot of archways and hiding spots. the ones i'm thinking of are

regal
blonde naso hopefully a male
powder blue
purple
achilles

any input would be good currently i have not had tangs because i felt a 55gallon was too small for them but they have always been fish i have wanted. additionally i'm thinking of getting a moorish idol. does anyone have good links to people experiences with them. i know they are one of the hardest to keep but i wanted to research they hell out of them before i make a final decision.
