Irwini get to 28inch, a cool mini monster that comes to mind is albino hemibagrus nemurus, asia but cool, they rarely pass 15inch and have the attitude and looks of the wyckii. Gulper catfish, giant bumblebee catfish, ornate pimlodus, black driftwood catfish. There's a few to get ya going!-) oh and apurensis but they get to 2ft and fat as ya leg...
