There's plenty of fun in owning one. But it's a lot more fun to own a school. This will keep them active.
And yes they do look impressive when they are big. It's hard to find pics here. but if you venture over to another site like "aqua coyotes" (use synonyms) then you can find them.
It all depends on what you are looking for in a fish. Hydro species are by far my favorite partly because of the way they hunt. I have owned fish that just frantically chase food running into everything like a starving hippo chasing a cheeseburger. I prefer something that "hunts" waits for the perfect moment, cautiously, waiting, still, and only strikes if everything is perfect. A sniper if you will.
