I'm not sure if I should post here so I checked if somebody did try ID'ing fishes in this forum first. I am not sure as to what type of fish it is.
Anyway, I saw this fish in my LFS a few weeks ago. I was fascinated and almost took it home but having no background with this fish, I stopped myself and said I need to do research first. I forgot I have a camera phone. Based on memory, I searched for images of this supposed "eel". After a few hours of searching, I decided it is an electric eel. So I told myself, I will not get it. Today, I looked at it again and found that the undulating fin is not an anal fin but a dorsal fin and no caudal fin. It is very much a BGK but upside down and minus the stripes. What do you think it is? The Chinese name as I have heard it is that of a knife and not an eel. <Sorry for the bad quality pic>
