I bought a tiny snowflake eel yesterday, and from what I've read and been told, thought it crawling out of the tank really wouldnt be a problem, I was wrong, within the first hour of the lights being out, it hit the floor, and traveld a good ways from tank, if i didnt happen to move something about 8 feet from the tank, it would've been way too late before I found it, whats the best way to escqape proof my tank?,its a 45 high, with just rock and 5-6" baby snowflake
