I am with you on a 15 tank! When I look at people's pictures or sometimes browse through the fishing forums I got so envy and have all those dreams and ideas and plans on how to buy a bigger aquarium and make it look awesome. But when I move my head, look at my 15 and think how much time I need to properly clean it, to make sure every fish is safe, that plants go unharmed and...well I am cured immediately ;)
