That guy is beautiful! I'd suspect that is some sort of oddball coloration, all of the tank raised ones I've seen have been solid black.

Moved to catfish.
Irwini name changed to uranoscopus. What I read is uranoscopus was the first described and named. Then Irwini was found and thought to be a new different species but later turned out to be the same fish so first name takes priority.
