How to select a silver arowana?

When choosing an arowana, observe its spirit and appetite; if it lacks energy, eats little, and likes lying on the tank bottom, it is generally not advisable to pick it. A healthy, active fish that feeds at the surface and even interacts with people is usually a good choice.

Next, check for scale loss, eye drop, underbite, or curled fins; if present, avoid it. Finally, observe its swimming posture and choose one with elegant movement, even speed, and a fully spread caudal fin.
