I used a CC when I started my first tank, a 29gal. Then I added a 55gal tank, also on the CC. It was about that time that I realized how much interest I was wasting on the CCs and school loans. I tore both tanks down saving key equipment and waited until last year when all my debt was gone to start again.
Now everything is pay with cash and I do as much fragging and trading as possible to keep costs down.
My wife said I could have a dedicated fish room in the next house and any selling I do out of this tank will be added up as a running total. Once I have enough credits in that running total I can upgrade. Pretty strict, but fair in my eyes, and my family and education comes first. Obsession...er Hobby...a distant third.
