Emily, I will see if I have pics of my leos 20 longs. I keep paper towels in mine, but I might switch to tile soon. I really like the tile in my beardie cages. It should be great for leos too.
We keep a mix of hide types. Their favorites are the black plastic hides you can buy at reptile shows-- cheap little things, maybe $3 a piece for the small ones. They love those stupid, ugly hides, even more than the caves.
Mine are kept in pairs, and we've had no issues with aggression. The females will go into egg laying from time to time and I simply throw the eggs away. I've raised baby cresties and we got too attached to sell them-- so last thing I need is to raise baby leos!
Here are some pics:
And our blizzard gecko, Ares.
Here is a close up of his eye. It's called eclipse eye.
