I've had my 55 gallon for about 12 years. Before that I had 2 10 gallon tanks and different times of my life. Through this time I have only encountered 2 other people that have tanks. One was my wife's sister who had a 10 gallon for the kids. The other is my wife's cousin who has a 120 gallon tank. Granted, when people come to my house they love the tank because it's so much bigger than what they're used to. I love my tank. For poops and giggles I've been browsing craigs list for the past 2 weeks just to see what's out there. I can't believe how many people have bigger tanks than I do. I see plenty of 75, 90. 120, 140, 150 and 210 gallon tanks for sale. Someday I'd like to have a LARGE tank, even larger then the ones I mentioned here. I just can't believe how many people have these larger tanks. I also wish I had friends and family here that were also interested in the hobby. It would be great to talk about it with them. Both of the family members I listed above live in Florida. I REALLY wish I had someone who had a saltwater tank because I'd love to get into that as well. I'm hoping that LARGE tank will be a SW setup but time will tell.
