"ne one", "u", "r" Come on, dude. Don't type like a retard.
I see those paper background things at all sorts of reptile shops. Hopefully you are using it for your own personal desire, because I'm pretty sure your tegu won't give a crap about the piece of paper on the back of the cage. Worry about whats inside the enclosure and how it meets the tegus needs instead.
About your reptisun 10.0 bulb being enough. You need to figure that out yourself. We have no clue where you are placing the bulb, how close the spot is to the bulb, or anything for that matter. Set up the cage and use a temp gun to figure out the temperature. Adjust as necessary. I'm pretty sure you won't need two bulbs though. Make sure you keep the humidity up or you will run into all sorts of problems.
And I hope for the tegu's sake that the "temporary" 55 gallon tank does not become its forever home. Plan on building something sizable around 4'x8' so the tegu can roam around.
"does ne one know where u can get a nice looking wallpaper of grasslands or some kind of picture that resembles a tegus natural habitat? im gettin a baby tegu and im trying to make the enclosure as close looking to its natural habitat as possible. since its a baby the enclosure would only be temporary, 55 gallon long tank. i have in mind wat the setup is gonna be in there im jus curious if there r ne wallpaper for the background or am i gonna have to "stitch" up my own in Photoshop.
also does ne one have ne idea if a reptisun 10.0 would be to much for a tegu or should i use two of those bulbs to be safe?"
