I actually started an LA club a few months ago (Los Angeles Aquarium Society) but I have always been part of several clubs.
I just moved to CA about 8 months ago from Texas. I have had many tanks, big ones too. at one time I had a 300, 260, 160, 60, 50 and a 10 gallon.
I currently have a 5 gallon nano I just started which you can see in my build thread here.
