brackish fish in a reef tank?

[spamreefnew]

I know many so called brackish fish are truly marine fish and several that are in fact brackish will do just fine in full marine systems. The prices and behaviors of many of the brackish fish I used to keep would be ideal for my reef IMO. here are a few I was thinking of : mollies,scats,dragon goby,mono sebe, ect


what are your thoughts?
