Since Justin posted his Monster-10, I guess I can post my Monster-15.
I like the stealth action, so I hid a 2213 in the dresser. This is my son's tank. There's not much in it now, but once he is old enough (he is 20 months now) he will be picking out his own mini-monsters.
Filtration = Eheim 2213 with a pre-filter module
Heater = 50W Hydor
Lighting = 12" 50/50 fluorescent fixture
