LOL I have 7 tanks at home and 2 at my parents house, as well as 2 ponds at my parents house, probably close to 10-15 empty tanks laying around, 2 holding snakes.... and I still want more. I am going to be breeding bettas hopefully by the end of this year, I'm currently looking for a 90gal, and I am dreaming of indoor ponds and at least a 220gal eventually.
Good Luck with not being overly addicted to the hobby! LOL
Keep in mind we are 20 something newlyweds with many other animals to take care of living on one income with bills, loans, leases, and debt LOL. While planning our wedding reception and house hunting! LOL (we got married in Dec.. and the reception's in Sept. Go figure, everything we do is to a different tune than most people LOL)
