These tanks are amazing! The doors open wide so you can arrange, feed, clean from the front. The screened top has the sliders in the back so you can hide your wires thru them & down behind the styrofoam if you so wish; it is in there good but can also be taken out if you want - in 1 solid piece. I have a few different brands and this Exo Terra is truly my all time favorite I LOVE it and best of all my Leo's LOVE it! Them being happy is the most important and they truly are happier in this tank.
