I also need help identifying what he is, although I assumed he was an Elephant Ear I would like to get specifics. When I found him he was in a Veiltail Cup (which he's obviously not) so I snagged him up. His left fin is a 'gimp' fin, which was either torn at one point or just naturally that way, since i've had him it's mostly grown back. :)

Dont worry, Derpy Fish passed away and is no longer in his tank, although they did fine together :)
