My husband gets major points for not even mentioning the third tank I set up and only mildly commenting on the fourth tank set up in three months. He was very leery of the first one until I informed it was coming out of my money not joint money. Now he just seems bemused. My one year old likes to bang on the glass and tried to get into the 5.5 gallon a bit ago. And my mom thinks I'm psycho. What do your families think of this hobby?
