Hiya
I do have a couple of my boys in 2 foot long glass tanks, but these are my lazy boys who dont do anything else except sleep, eat and visit the 'toilet corner' - they dont touch anything in the tank really - it is all left the same as when i put it in the tank and they rarely need cleaning out except for the toilet corners (they still get cleaned out every two weeks though!)
I think this size tank is ok for lazy boys, but i wouldnt like to put any of my mad females in - it would just be too small for them as they like to mess things up, rip things to shreds and run around alot!
From the sounds of it your female is quite active and energetic, so i think a 3 foot tank would be a much better size for her - and yes, it does stop bar chewing
glass thanks are great for that!!
