Sam, enjoy your eel. I had one for 2 years and had a great time. He did take a fish or 2 :-) I got to see him wrestle a 2" in clown.......... Was worth the money lost on the clown :-) It was a 5 minute fight. Moved most everything in the tank. I got rid of mine once I started getting a lot of coral. The eel will move, break, destroy most things that can be moved or broken :-( If I can find a little snowflake, I may get one for my 20 Gallon tall. I strongly suggest you cover the tank. and, of course, to keep the eel in cuts down on the light for the coral......... always something :-) PS To get my 24" eel out of the tank. I used a fish hook and line tied to a toothbrush. I wish I had a video of that :-)
