I tried feeding him pellets and he doesnt it like them...I tried market shrimp and it doesnt seem to work either...What do u guys think I can feed him?? I jus got him 2 days ago hes 13 inches...
Just stick with the pellets, he is big enough to go weeks without eating. If you don't get him eating pellets now then you will have to starve it later to do so. Some arowana will take upto a couple weeks to get comfortable enough to eat, so don't worry about it.
