Help on idea for predator fish stocking?!

[DrewMChang]

Okay so I'm trying to start my fish tank. I have a 60 gallon. But I'm creating a 150 gallon right now. I need help on fish ideas. Red belly piranhas? Spotted Gars? Or Jardini arowana. I want an entertaining fish choice not just when feeding. Any other suggestions? I was looking into wolf fishes also.

So many options its hard to say. do you want 1 big one or many smaller guys? Exodon Tetras are probably more interesting than piranha. Do you want aggressive or predatory?

I'm vote for Exodon too, it's colorful and more active and LESS or NONE skittish behave compared to Piranha, feeding time much more fun than Piranha but Exodon required planted tank while Piranha mostly in bare tank.
