Thanks for all of your help!
As far as the tank goes, it really wasn't that much (Under 30), and I just wanted a covered system because I do have cats. I saw some cheaper conventional rectangular aquarium setups without covers and all the covers were pretty expensive.
The bubbler is not silent, but seeing as how its sitting near my computer it might as well be, I can't hear it over the sound of the computer fans. I'm more concerned about the fish not liking it, is there any easy way to tone it down a bit?
I figure this is a good beginner's setup with 1 fish and then I will possibly move on to bigger and better things later.
The tank is now conditioned and heated to a nice 78 degrees, so hopefully my betta will like it! I will be getting him in a couple of days.
Thanks again for all your help, if I have any more questions I know I can count on you guys.
