i would also say yes. they tend to be more forgiving with water conditions and they are better suited to the aquarium because they were raised in it. also they are used to aquarium food. i dont know about the being more resistent to disease thing though, ive been told the other way. i was told that since the fish havent been exposed to as many diseases in the aquarium then they havent built up as much immunity towards them. but i still would highly recommend the tank raised.
