The Rope Fish, Erpetoichthys calabaricus, is one of the Polypterids...a group of African fish. It commonly reaches lengths in excess of 76cm (30 inches) and is not really suitable for a 10 gallon tank.
I'm not quite sure I follow your reasoning when you say that you "cant find ANY small fish that arent hideous and can keep my attention ". There are virtually hundreds of different types of fish that are small enough for a 10 gallon tank that are beautiful and fascinating. What is it that makes a fish "cool" for you?
