To me it's a hobby. There was a free 44g corner tank on craigslist that I was going to pick up until my wife threatened that I better not get it...but most my honey-don't-know money goes to my fish etc.
Quick story, picking up stuff at a the fish store, and the poor employee was explaining that the pleco wouldn't really work in the 5g tank with the betta. At which point I chirped in 5g? just do a water change, the woman looked at me like I had 5 heads...water change on a 5g!!! I don't have that kind of time.... <facepalm>
