You really don't want to know how many fishtanks I have. They are not all up right now, though. For good reason...I had all of them running at one time, but that was pre-Mira and many moves ago. Ironic story...I had to leave a 29g behind in our last move. Just wasn't room in the truck, and I had another. Then we end up buying this house...we move in and lo and behold in the attic was an abandoned 29g. It's fate I tell you . And a few days later one of Dave's family members found out they were pregnant and dropped off their 50g and said, "do with it as you please, I won't have time." So not only was the 29g replaced, but we went UP one glass box. Weird.
