I know it is not necessarily ideal, but I could not pass up the opportunity to buy a $30 55 long gallon aquarium from a buddy of mine. I plan on having the entire top of the aquarium screened and also plan on removing one of the side glasses and replacing it with a screen for extra ventilation. I have two options really here. I have her in a twelve by twelve by eighteen terrarium currently. My first option, and question, would be possibly just setting up the 55 on its side. This way it is now 48" high as opposed to 48" long. Again, I would set it up so it would be well ventilated and more than likely increase the wattage on my basking bulb to provide a little more basking heat for the bigger tank. Any comments or even just a flat no would be greatly appreciated on this idea. My second choice would be to still use the 55, but leave it long. Now if I did this I would probably take the old terrarium and actually set it on top, seal it, and then that would obviously add another foot and a half of height to at least a section of the 55. Obviously this would require a little more work, and possibly two separate basking bulbs -- one for one far side of the 55 and one for the top of the old terrarium (Not sure if this would be necessary yet). I do provide it with UVB light nearly 24/7 because when I took her in she had metabolic bone disorder. Seems to be getting a lot better. Just to throw this in I am all set and familiar on all the care for them and what is required, I work at a PetSmart (Not that that makes me an expert, which is why I am here seeking some advice.) Any suggestions on the terrarium situation again would be greatly appreciated, so far I am leaning towards idea number one as long as nobody sees a big problem with it. I know this was lengthy, but thanks a lot to anyone who can help me.
