A Long time ago I had 17 aquariums... back in the 80's when I was breeding african cichlids. The aquariums were smaller, with the biggest around 120 gallons. Got divorced and sold them all off.
Fast forward to the early 2000s and I ended up with 10 aquariums. Biggest being a 180 gallon, then there was a 120, 60, dual 55s, and some smaller ones. Was getting another divorce after 16 years (is it the aquariums?) and advertised them on Craigslist for free.... come and get them. By the end of the following day everything was gone... aquariums, food, hoses, air pumps, filters, all supplies. I had nothing aquarium related left.
Over the last 18 months I have gotten back into aquariums again... in a bigger way than ever. Currently have a 700, 300, 200, 75, & 65.
