display tank, maximum size you're comfortable with

[reeferious]

everyone, including me wish we could keep and maintain magnificent display tanks large enough to swim in. practicality then kicks in and we limit our tank size to what we are comfortable with in regards to setup costs, ongoing maintenance costs, space limitation, protestation from others who share your living area etc. well mine is 90 gal display, 75 gal sump with additional 50 gal tote for additional water volumn. what's your? feel free to give details and explain why you wouldn't go any bigger or smaller.
