So I recently got my Silver arowana last monday. Today was the first time he ate because he's been trying to eat tetra pellets and shrimps but spits them out so it made me buy hikari foodsticks. What I notice about him is during the morning time he is very skittish and when it darkens out around 9pm he is very tamed and eats out of your hand. What should I do for him to act normal all the time? He has some floating pingpong balls and he is around 3-4".
