That's a pretty impressive list so far. Mine would be an Arapaima gigas.
Just to let you know what started this...I was checking out John's webcam with a buddy of mine and I said that if I could have any setup I wanted I would get a tank big enough for an adult gigas. I would set up a fat comfortable sofa accross from that bad boy and just let the days go by.
Maybe someday when I have a house, but I don't think the landlord will allow any more tanks in my apartment...as well as my girlfriend.
I had to make an important decision the other day...set up another ]V[onster tank, or invest in and engagement ring for my girl...I chose wisely...I chose the fish.
