hey, i've been toying with the idea of finding something scaley to put in my empty ten gallon, and after some looking, am thinking a single leapard gecko would be a good fit. i've read that a ten gallon for one is fine, if i take advantage of vertical space, but i'm still a little bit confused on feeding, lighting, and substrate. 1. what do i need for lighting? 2. can i use sand, or will i need to find something else? 3. what do i need to be feeding and how often? i know mealworms are a must, but i'm confused about wether crickets or anything else is going to be needed. 4. how do i prepare food like mealworms and crickets? 5. if i am to feed crickets... what should i keep the crickets in? 6. this is sort of a silly question... but is it safe for me to hold it every once in a while, or will i injure it? sorry for all the questions... never dealt with reptiles before. thanks in advance!
