Black Ghost Knifefish is your winner, people who aren't familiar with the hobby and are used to goldfish tend to be awed when they first see a BGK, even more so when it grows out![]()

+1 I saw one of them at my dads friends house when i was little. That exact fish got me into the hobby. But they grow soooo S.L.O.W. Mine is 5 years old and has only grown 4". Very slow growing but long lived. However they tend to be shy at first and a fish that people can not see will not start conversations.
