Can't wait for the vids, and for him, LOL. All of the options are pretty rare, and I'm thinking that it's G. tigre, G. anguillaris generally has it's stripes closer together, and G. tigre usually is of lighter color like the one pictured... but there are several undescribed Gymnotus species too, and some of them look very similar as well. I'm hoping for G. tigre, though. 
and any of the rare fish that were going to Japan were watermarked by AquariumPAEX, so I don't think im allowed to post the images here..
