Im not sure about that being bs. But i do know DE is not genetic. DE is caused by the fish which keeps looking down in search for food tht sinks, for example prawns. Breeders here use crickets for food as they float. So the way i understand it is that cricket which floats made the arowana looks up and prawns which lies at the bottom of the aquarium made it look down. So ping pong balls might idk nvr tried it before. Have u cared for an arowana before?
ps. not the best color but nevertheless its still a cool fish.
