Im building my first viv. Its 6x2x2 so its fairly long. Im just wondering. Where should i put the vents? I was gonna add them to the sides but i feel the heat could get trapped by the 6ft roof. Im thinking maybe 2 2ft vents ontop? The top would be best for cosmetics because i plan to make a fake rock background and i really dont like seeing vents on rock. Not very naturalXD i would totaly post a pic. But im not quite sure on how to right now. But its a basic melamine box with no front or back. Front will be glass sliding doors and the back will be thinner wood or mdf board. Thanks a lot
