Yes, I did some repeats in the second post. I figured the first response would be "do you have any better pictures?"
Picture four in post one is the same fish as picture two in post two.
One and four in the second post are the same fish.
Picture two in first post is the same fish as picture three in post two.
After looking at the links, I agree about the Panaque nigrolineatus, the Asian catfish and the Synodontis eupterus, but I'm not sure about the other two.
Sorry for the confusion and thanks for your help!
