When i get an actual desk I'm going to want an aquarium on it, and was wondering what would be possible options. It'll probably be around 5 gallons as I'm going to need space on the desk for my gaming setup, so don't want it to take up a ton of space. Also of course I'm going to move the gaming stuff off of the desk when i clean the tank so I don't get water on it. Any suggestions? I want something that will be active to look at while I'm bored doing online school or waiting for the next match in a game, so try to avoid the fish that'll just sit there and look pretty. I want something that does stuff.
