My son (11 yrs old) had a 14 gallon freshwater tank in his bedroom, but the window was just in the wrong place to have a tank in his room and the algae was uncontrollable. Another problem was that my 3.5 and 2 yrs olds were always playing in it lol. Tonight I set the 16 gallon bow front that used to be my saltwater tank up in the living room so the kids cant play in it. Currently it just has his 3 guppies and 3 neon tetras in it. It has blue (his favorite color) gravel for substrate and the Aqueon Power Filter 20 on it with no light. The filter came as part of the 14 gallon kit. I also have a 50 watt heater in there. I don't currently have any plans for this setup right now until he tells me what he wants. I would love to make it a planted tank, but we will see. He really likes sponge bob, so I'm sure it will have that theme lol. I will try to get some pics up tomorrow.
