If everything is that expensive there you might want to look into something else. You are going to spend so much money on lighting just for one anemone. They are pretty difficult to keep and if you are asking things like "do I need a thermostat" you should probably just start slow and try your luck keeping a pair of clownfish and 6-9 months later when you have learned more, then think about getting proper lights, a protein skimmer, and then an anemone. I don't mean to put you down or anything but saltwater inverts are very delicate and you need to be patient and take everything slow with saltwater, otherwise you'll just be wasting money. www.reefcentral.com has a forum specifically for clowns and anemones where you can get all kinds of answers to the questions your asking. Check it out and by the time your tank is ready for an anemone you'll be an expert on them.
