I don't even want to try listing sizes anymore. I have 120 tanks. The average size is 450gals. Picking up a 100gal this weekend to bring the number to 121 tanks.
I have 8 right now, but when I move I will be cutting down the number, but keeping the total gallons the same (ie I will be selling a bunch of my smaller tanks to raise funds for a 150 or 180)..
I have a 90, two 65's, three 30s, a 20 and a 10 right now..
