I take it this has been asked before? 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.
I think they are a color morph as i have breeding Leporacanthicus sp. that will have a few funny blotches in white color.Nothing like that picture yet but i am working on it.
Not in large quantity at all. I think in ones or twos. That's why the price is literally crazy. From what is said they all go to Japan. Imagine what they are paying lol
