any eel is known to climb out of a tank from time to time lol
the price ranges depending on who collects them there is a good guy on ebay who sells them at a good price shipped to your local FedEx where you can pick it up
I had one and it got out once. I was to blame though as I left the cover on my tank open. Other than that, an excellent eel who I was able to see everyday and fed3 times a week with the use of a feeding stick.
