American tigerfish aren't actually American, they are basically a silver dats that max out at 12 inch, check if they are OK in freshwater all their life as some datnoids prefer brackish...
Four-line pimlodus is an option, nice active pretty fish, fairly common and max out at 12 inch. Ornate pimlodus is similar, little rarer and more expensive.... Asian Suncat is another option. All great little/medium catfish.
