I had a 6" Juruense catfish. The previous owner got him at 3" and sold him to me at 6". When he was young, he would sit perched on a large Anubias leaf all day and wouldn't eat until the owner turned the lights off. He was very peaceful and calm.
When I got him, he would perch himself on a large rock and sit facing the powerhead with his whiskers spread out waiting for food to come by. He never caused any problems and never swam into the glass. However, when I redecorated the tank and the perch disappeared, he spent a fair amount of time swimming up the glass. I've seen them do this in LFS too and it appears to be because they need to have places to perch themselves during the day.
Mine eventually died of a really bad case of velvet that got under his skin.
I do not have any experience with anything bigger than juveniles. They are beautiful fish (much nicer than Tigs IMO), but the eventual adult size is more than my 165 could handle.
