New to SW

[giffmastaflex]

Hello,

I have a 55 gallon FW tank and I saw that Petco has a deal where it's a dollar a gallon for a tank and I was thinking of getting the 55 gallon to build a SW. The only thing is I don't know what I'm getting into. If you could please give me some information on how to be successful with the tank and also some fish suggestions would be great. Also some pics of your tank to get some ideas on what I can do with the setup.
Thanks
