Some species, however, need to be provided a large tank from birth though. Even when the fish are small, they need to be provided a lot of swimming room or else they become extremely stressed and their growth become stunted. I do agree with you though that people can put a small fish in a tank that will not be suitable for them when they are fully grown if they will be upgrading, but the reality is that the person will most likely NOT upgrade and will think the fish is doing fine since it is not growing large. That is why it is recommended for people to just go ahead and get fish that are suitable for the tank size they have, especially to people new to the hobby.
