for me it started when my buddy had put up his 30gal tank. i was like sweet, i had a 50gal so i set that up. so he went and bought a 85. so i bought anouther 55. so he bought a 110. so i bought a 220. then i bought a 60, then a nano. about a month ago he said he was buying a 280. so i ordered a 540. i guess it will end when one of us gives up....or when i run out of room....im close. i already tossed my end table for my hex, then i threw out my dinning room table for my 220 (we eat on the couch). now im throwing out my bedroom dresser to fit my 540. i guess the couch is next.
