I saw the descriptor, but the vid was posted in 2006, so I was hoping more info had come to light...Looking at the fish, it is definitely a Leporacanthicus sp...not Hypancistrus.
Leporacanthicus sp. "Black and White" is an inofficial name I've heard.
Expect the movie on youtube, I haven't seen any of those!!
There are several rumors about this fish.
1. Mutation in nature and has just been found once in Venezuela
2. Fake
3. Has now been found again in Peru but not been imported yet.
I prefer #3 and still hope we will get this fish in near future
