I love that guy And He's tough as nails. I came downstairs a while back and saw something on the floor and sure enough it was the eel, he had traveled through the return tubing from my fuge and snuck out from there. He was pretty lifeless but I put him back in the tank figuring he would die from infections in a day or two but about 10 minutes later he was back to normal. Then a day or two later I see my Porky Puffer spinning around in front of the pvc tubing I put in for the eel to hide in and sure enough the puffer had him by the head. I got my algea scraper and distracted the puffer til he let go and the eel slid back into the pvc. I wish I was that tough! When I got him he was about 5"and only cost $6.99 now he's about 10 or 12" long. He also loves to hang out in my oveflow box.
