after all the nano hype i got a 24 g. and it is more fun than my 150g. ??? all the cool small fish and corals, a 150 is hard to play with evey thing needs to be so big, and $$$$$ the nanos are awsome and for $200 to start it, chhep way to get in to salt, I should see if they are public and buy stock, this could be a huge x-mass gift for people.
