so i have a glass enclosure for my lil pepito till he gets a bit bigger then were gonna place him into a much larger sceen enclosure. well this glass terranium has a styrofoam slab shaped and colored like stone for the back wall. behind the wall are 2 cutout strips going downward for those animals that need heated rocks and so forth so you can hide your cords. goes in holes at top of terranium, goes down back of rock wall, out hole at floor. well i dont have any flooring in my terranium i was told to leave without being as it will be a breeding ground for bacteria. so i didnt get any, well the crickets like to crawl in hole at floor climb up back and sit on top of styro foam rock. where i am afraid lil pepito cant get or see them. and some chill behind the wall entirely, and die! I taped up the holes at the roof to prevent them from jumping out of tank but what can i put at the holes on the floor to prevent them from hiding from pepito?? please help!
