We’ve all got that friend who has tried and tried to keep an aquarium, only to have fish die within days and an empty , torn down tank within a couple of weeks. And no matter how much advice you give or how much help you lend, the aquarium just won’t look right and won’t sustain life. For these situations, the best thing you can do, as a responsible aquarist, is to encourage your friend to pursue another hobby. There is no sense in letting hundreds of dollars worth if fish perish and let thousands of dollars in equipment collect dust. Not everyone is cut out for this hobby.
