So, I'm thinking "stargazer" -> Astroblepus,
Smart cookie.
The species clue:
My fish is from another continent and has no keepers. One of his pictures looks like he's about to be served for dinner! We've only seen this genus once before.
The species is one letter off a famous writer that used to be a physicist.
torbanite got the 'cobble together' clue, now remember how catfish are often named, especially ones of certain geographic locals..This physicist might see this fish if he went for a weekend trip!
We're looking for a name that is one letter off the writer
and an object. The writer would have to stay on the west coast of a continent and go north almost to the equator, about 10 degrees or so. He couldn't walk that far, he would wear out his shoes.
The writer isn't that important if you have the other species clues. If one knew of the writer, he would have popped to mind but unlike someone like Hemmingway, most people would not have heard of him.
Racing, shoes and fish. Nothing else matters. Oh, and bacon.
