Giving an aquarium for a gift unless the person expresses a big interest for one is a mistake. Even the people giving the gift probably don't even know the work and time involved, and the end result is that it starts off with people thinking it's just a matter of adding water, adding fish, and sitting back to enjoy. When they find out the truth, the tank ends up collecting dust in the shed or in a yard sale.
I practically begged for an aquarium for my 15th birthday, but I was already learning as much as I could before I asked. That' the exception, though, not the rule.
