Hi all, got a new silver arowana that's about 5 inches long and he's eating crickets, krill, plankton and blood worms but now I want to switch him over to pellets every now and then. I've tried numerous brands and he's been eating all of them and then eventually spits them out, alot of people online recommend starving them for a few days but I don't know if this is safe for a small arowana. Anyone have any ideas or input for me? Thanks
