Suggestions for a fish for a 65?

[recoiljpr]

I've been going back and forth for a while as to what fish I want to be the last one I add to my 65 gallon.

My wife really wants a yellow tang, but I'm not sold on the idea. I've spoken to quite a few people who in their opinion I can do it; but I just don't fully feel comfortable with that in my gut. My wife about died when at a LFS a tang basically laid in the employees hand. But, in then end after thinking more about it, I don't want to do it. So I will need to find something that I'm fully comfortable with and will also give her that "dog" disposition.

My current fish list is -

2 medium False perc's
1 Diamond goby
2 small Chromis

All that being said I know all fish have their own personalities and that can differ between individuals. But, I'm looking for a generality here to start my research with.

So, I'm looking for something that I can put in my 65 that is active, friendly and has a general outgoing disposition. I also have SPS corals and a clam so it needs to get along with them. It also needs to semi-large, but small enough to be fully comfortable in a 65.
