I'm planning on getting a Leopard Gecko within the next month or so, and it will be my first reptile pet. I work in a pet store myself however we don't sell reptiles, but I do know a fair bit about them. We do sell everything, from live food to terrariums (which I get 20% discount on!) as well as having a reptile vet in store, so my gecko will be completely sorted I would like some advice on what substrate to use, I'm really leaning towards tile but I'm not sure what type. I've also considered eco earth, reptile carpet and excavator clay. I've done a lot of research but people have so many strong opinions I've heard bad and good things about all, what's the best natural looking yet safe substrate to use? I will be getting a medium sized terrarium that is 60x45x30cm for 1 gecko, I did want to get a large as I first thought more space the better, but I've read that they can get stressed with too much space. (I do plan on getting a heat mat that is half the length of whatever tank I get) Are 2.0% UV ray lights necessary for my gecko? if they can potentially cause more harm than good, I will not get one. Any advice or tips will be much appreciated!
