wow.. I love the hobby but you guys are Freaks (in a good way) lol I only have one at a time.. set up that is. right now its a 110g. I still have my old 45bow front in storage. a lady at work is supposed to be buying it. I Have had, in the past, a 1 gallon, 10g, 20g, 45, now the 110. When I was living with my parents we did have two up. My 20g (then the 45 I bought) and my dad's 55 hex. When I went to college I had to move my, then 20g, downstairs for them to take care of it. After I graduated and moved back I bought the 45Bow. Always chiclids or Piranhas..I did make the switch to Salt for about a year...but I switched back. As pretty as SW is, I much prefer Freshwater!
