i agree, that you can fool some fish into thinking its not in a tank if the tank is big enuf compared to the size of the fish, like some barbs in a 30 gallon, im sure they dont mind, but come on people, putting a few fish in a 5 gallon, thats like puttin a monkey in a closet for all its life, when it should be outside living in trees eating fruit. just my 2 dollars.. :OT:
