If anyone knows Uaru (pretty sure that's how you spell it), you know they are sometimes called the poor man's discus because of how similar they behave and how similar their care is. Now, I want to know if there's anything like a poor man's Arowana. I want to know what behaves like an Arowana, but is cheap and stays small (8 inches or under), and is not hyper aggressive. If you know of anything, please let me know (if you can post a picture as well, that would be great).
