definitely not a leo! those little guys (whose species is slipping m mind right now) are native to where I live, and you've got a baby one right there! they are about 3 1/2 inches when adults. I really rally recommend letting that baby go, because from my experience thy are super delicate and wll die very easily of shock when you try to keep them as pets (I tried ALOT when I was youngr) plus if you let it go outside of your house, it will hang out by porch lights and eat all those freaky bugs around the house during spring and summer! then you will have a cool night time companion, and free pest control! haha! ither way, I hope this helps you out
