I don't mind the hijacking. This thread and many others of our fun little group are full of lots of tank related and non tank related stuff as I'm sure you are aware by reading through mine. We can get a little crazy on here sometimes. Your setup will work to get you started, but start looking now for what you think your build would look like when its time to upgrade (upgrade doesn't always mean bigger, might just be better). Start researching costs, differences in equipment, lighting, skimmers, and anything else you will need. I bought most of my equipment used to save costs. Getting your wife involved is a great idea.
@Mrs.F i s h y loves our tank, says it isn't big enough. Start the conversation about getting a new set up sooner rathe than later. You can set an amount to save each paycheck and stick to it and have a goal in mind for a date to upgrade. It will help to keep you fueled in the hobby and learning as much as you can. If you and your wife both take the time to learn the equipment and things needed to be successful she will be way more willing to help with the planning of the new setup.
