these are my favorite eel.Wife put one in when it was just 4 to 6 inches long.Great lil additon tell he grew up.When we finally cought him he was about 18 inches long and ate 9 chromis,8 emrald crabs,two cardnials and a clown,it was way cool to watch him ambush fish !!He is now lord of the fuge and loves squid and is getting bigger evryday !!
