Hi Goffy! Yep, with those sliding doors all the way to bottom you will have an issue with substrate falling out and any splashing water exciting through door crack. You could glue in a glass strip across whole front creating a "dam" like wall... but why go through all the hassle? That same company sells a similar sized doorless one with top access that I think is more suitable to a Pyxie: 888 Reptiles - Komodo Reptile Habitats Top Opening 60 x 30 x 46cm. Also you could look at aquariums with a ventilated top. Not sure what size is your male; but be aware that if he grows really big; might eventually need a larger enclosure. Good luck!
