I have to agree with the others about the skimmer. I would not pay more cash for fish until I had the equipment side squared away. Not all skimmers are $300 either. Ipaid $130 for my eshopps skimmer brand new. Theres also craigslist which always has used skimmers on it.
Using a bicoube skimmer on a tank that size is just wasting electricity in my opinion. lol Its a horrible skimmer even on my 29g biocube. LOL
But seriously, there are things you should be prepared for in saltwater such as the cost. :-( And all those supplements are useless pretty much as well, save your money. There is nothing that you can dose for that is NOT in your salt mix. So if youre doing regular water changes then you are set, no need to add anything until you literally have a tank full of coral.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
