Ill say starve him and he will start eating, another thought would be super worm. Arowana love them, its like crack.
How exactly do you starve a fish that is not eating? Are you suggesting to stop offering it food?
Yea. Starve it for a couple days to a week & then feed it. They can go weeks w/o eating. Be patient. As long as it looks healthy & active, dont wprry about it
I can't imagine seeing you with an African Arowana.YUP!
I raise several different arowana and when they wouldnt take food, i just left it alone and stop feeding it. In a week or so, they go gaga! Always does the trick.
